Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

Abstract: A circuit diagram and an equivalent circuit of high-input-impedance buffer stage with bootstrapped input biasing resistor and power supply nodes are given. The efficiencies of the ...

We’ve previously remarked upon a generation lucky enough to be well-versed in microcontrollers and computersised electronics through being brought up on the Arduino or the Raspberry Pi but unlucky ...

Abstract: A 2 GHz SiGe:C HBT low noise amplifier (LNA) with improved gain compression and linearity performance is described. A modified resistor bias feed circuit for the LNA transistor improves its ...

Most of electronics deals with Tracing Curves, be it the characteristic transfer curve for a feedback loop, a resistor’s straight VI line or a transistor’s collector voltage versus current curve.

The complete circuit diagram for Dual Channel Pre-Amplifier consists of two mono circuits combined to form one stereo circuit as shown in the image below. As you can see the left channel audio, and ...

FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...
