    High Speed Comparator Techniques
    The AN13 is an extensive discussion of the causes and cures of problems in very high speed comparator circuits. A separate applications section presents circuits, including a 0.025% accurate 1Hz to 30MHz V/F converter, a 200ns 0.01% sample-hold and a 10MHz fiber-optic receiver. Five appendices covering related topics complete this note.

    High Speed Comparator Techniques
    Jim Williams
    INTRODUCTION
    Comparators may be the most underrated and underutilized monolithic linear component. This is unfortunate
    because comparators are one of the most flexible and
    universally applicable components available. In large
    measure the lack of recognition is due to the IC op amp,
    whose versatility allows it to dominate the analog design
    world. Comparators are frequently perceived as devices,
    which crudely express analog signals in digital form—a
    1-bit A/D converter. Strictly speaking, this viewpoint is
    correct. It is also wastefully constrictive in its outlook.
    Comparators don’t “just compare” in the same way that
    op amps don’t “just amplify”.
    Comparators, in particular high speed comparators, can
    be used to implement linear circuit functions which are
    as sophisticated as any op amp-based circuit. Judiciously
    combining a fast comparator with op amps is a key to
    achieving high performance results. In general, op ampbased circuits capitalize on their ability to close a feedback
    loop with precision. Ideally, such loops are maintained
    continuously over time. Conversely, comparator circuits ...

    Thermal Techniques in Measurement and Control Circuitry
    Jim Williams
    Designers spend much time combating thermal effects in
    circuitry. The close relationship between temperature and
    electronic devices is the source of more design headaches
    than any other consideration. regulator’s output low, biasing Q1. As the heater warms,
    the thermistor ’s value decreases. When its inputs finally
    balance, A1 comes out of saturation and the LT3525A pulse
    width modulates the heater via Q1, completing a feedback
    path. A1 provides gain and the LT3523A furnishes high
    efficiency. The 2kHz pulse width modulated heater power
    is much faster than the thermal loop’s response and the
    oven sees an even, continuous heat flow. In fact, instead of eliminating or compensating for thermal
    parasitics in circuits, it is possible to utilize them. In particular, applying thermal techniques to measurement and
    control circuits allows novel solutions to difficult problems.
    The most obvious example is temperature control. Familiarity with thermal considerations in temperature control
    loops permits less obvious, but very useful, thermallybased circuits to be built. The key to high performance control is matching the gain
    bandwidth of A1 to the thermal feedback path. Theoretically, it is a simple matter to do this using conventional
    servo-feedback techniques. Practically, the long time
    constants and uncertain delays inherent in thermal systems
    present a challenge. The unfortunate relationship between ...

    Operational Amplifier Selection Guide for
    Optimum Noise Performance – Design Note 140
    Frank Cox
    Eight years ago, George Erdi wrote a very useful Design
    Note (DN6) that presented information to aid in the
    selection of op amps for optimum noise performance,
    in both graphical and tabular form. Design Note 140 is
    an update of DN6. It covers new low noise op amps as
    well as some high speed op amps. Although a great deal
    has changed in eight years, especially in electronics,
    noise is still a critical issue in op amp circuit design
    and the LTВ®1028 is still the lowest noise op amp for
    low source impedance applications.
    The amount of noise an op amp circuit will produce
    is determined by the device used, the total resistance
    in the circuit, the bandwidth of the measurement, the
    temperature of the circuit and the gain of the circuit. A
    convenient п¬Ѓgure of merit for the noise performance
    of an op amp is the spectral density or spot noise. This
    is obtained by normalizing the measurement to a unit
    of bandwidth. Here the unit is 1Hz and the noise is reported as “nV/√Hz.” The noise in a particular application
    bandwidth can be calculated by multiplying the spot
    noise by the square root of the application bandwidth. ...

    3V Operation of Linear Technology Op Amps -Design Note 56
    George Erdi
    The latest trend in digital electronics is the introduction
    of numerous ICs operating on regulated 3V or 3.3V
    power supplies. This is a logical development to increase
    circuit densities and to reduce power dissipation. In addition, many systems are directly powered by two AA
    cells or 3V lithium batteries. Clearly, analog ICs which
    work on 3V with good dynamic range to complement
    these digital circuits are, and will be, in great demand.
    Many Linear Technology operational amplifiers work
    well on a 3V supply. The purpose of this design note
    is to list these devices and their performance when
    powered by 3V. The op amps can be divided into two
    groups: single and dual supply devices. The single supply
    op amps are optimized for, and fully specified at, a 5V
    positive supply with the negative supply terminal tied
    to ground. Input common mode voltage range goes
    below ground, and the output swings to within a few
    millivolts of ground while sinking current. Members of
    the single supply family are the micropower LTВ®1077/
    LT1078/LT1079 single, dual and quad op amps with
    40μA supply current per amplifier, the LT1178/LT1179 dual and quad with 13μA per amplifier. The LT1006/
    LT1013/LT1014 single, dual and quad have faster speed ...
