81. A pitch-linear VCO. Part 2 - Taking it further
    Nick Cornford
    Articles Texas Instruments CD4013B CD4015B CD4013B
    In Part 1, we saw how to make an oscillator whose pitch, as opposed to frequency, can be made proportional to a control voltage. In this second part, we’ll look at some alternative ways of arranging things for other possible applications. To ...

82. Use current-mirror biasing to avoid squegging in RF oscillators
    Madhu Siddalingaiah
    Circuits Texas Instruments LM3046
    If you've ever designed an RF oscillator, you've probably encountered squegging. Sometimes called motor boating, squegging causes oscillators to start and stop at frequencies much lower than the frequency of interest. Viewed on an ...

83. Three discretes suffice to interface PWM to switching regulators
    Stephen Woodward
    Circuits Texas Instruments TPS54332
    It’s remarkable how many switching regulator chips use the same basic two-resistor network for output voltage programming. Figure 1 illustrates this feature in a typical (buck type) regulator. See R 1 and R 2 where: Quantitatively, the V ...

84. Simple setup tests bit-error rate
    Israel Schneiderman
    Circuits Texas Instruments LM393 SN74HC74 SN74HC86
    Traditionally, the reception quality of a digital receiver is expressed in terms of BER (bit-error rate). This figure is the proportion of received bit errors in a given period. Typically, you measure the BER in the lab by applying an RF signal, ...

85. Flip ON flop OFF
    Stephen Woodward
    Circuits Texas Instruments CD4013B
    Toggle, slide, push-pull, push-push, tactile, rotary, etc. The list of available switch styles goes on and on (and off?). Naturally, as mechanical complexity goes up, so (generally) does price. Hence simpler generally translates to cheaper. Figure ...
