This circuit was born from an application that required an input signal to be precisely clamped to less than 2.5 V, while operating on a 2.5 V supply with a maximum output of 4 mA...
Precision clamp protects data logger
SiTime Enables Up to 25% Faster Wireless Charging with MEMS Timing Solution
SiTime Corporation introduced the SiT3901 µPower digitally controlled MEMS oscillator targeting power-sensitive and space-constrained mobile and IoT applications...
Circuit forms random-bit-sequence generator
A random-bit-sequence generator is basic equipment for prototyping and testing any data-transmission system. You use such a generator when measuring BER and pattern-dependent effects in a transmission system...
Zener diode and MMICs produce true broadband noise
A broadband source of white noise can be useful for measuring and testing communications equipment...
Pushbuttons and digital potentiometer control boost converter
Digitally controlled potentiometers are useful for generating analog control voltages under the control of a microcontroller. In some applications, manual pushbutton switches could replace a microcontroller and simplify product design...
10 analog design icons that vanished in the 21st century
Analog semiconductor acquisitions are all the rage. After the golden age of analog design innovations spanning across the last three decades of the 20th century, an era of consolidation began with the turn of the 21st century...
Scheme cancels amplifier error
The circuit, using a low-offset amplifier, is a basic ohmmeter circuit common in multimeters, except for the addition of the two diode-connected transistors. A current source supplies a selectable current...
Instrumentation amp works from one supply
Many single-supply applications need precision amplifiers that can operate from 5 V or lower. Although many precision, single-supply op amps are currently available for configuring as 2- and 3-amplifier instrumentation amplifiers, these designs require great attention to detail...
Op amp can source or sink current
When you design for electronics applications, such as sensor or amplifier bias supplies or special waveform generators, a controlled constant-current source or sink circuit can serve as a useful building block...
Why limit your power supply's input range?
Taking only a cursory look at the input-voltage ratings of your power-supply IC can limit the usable input-voltage range. With careful examination of an IC's operating specifications and circuit topology, you may be able to work around that input-voltage limitation...
