The final part of this series will start with bias servo circuits for automatic set up. The FETs pinch off or threshold voltage can vary widely for the same part number. Depending on the fabrication ...

Biasing an active device, such as a bipolar junction transistor (BJT), requires that you set the dc voltages and currents of the device. To optimize the desired result, you need various bias values.

Bias circuits for class AB buffers (Fig. 1a) can take several forms. One alternative (not necessarily the best) is usually called the “old VBE doubler” (Fig. 1b). The main purpose of these circuits is ...

In some power-supply applications, the pulse-width-modulator (PWM) controller is powered up from an auxiliary winding tapped off the power stages transformer (Fig. 1). This technique reduces power ...

A new technical paper titled “Cryogenic-Aware Forward Body Biasing in Bulk CMOS” was published by researchers at QuTech, Tu Delft. “Cryogenic CMOS (cryo-CMOS) circuits are often hindered by the ...

This paper presents the practical application of body biasing control of ultra-deep submicron FD-SOI technologies for analog and mixed-signal designs. The body biasing control is dedicated for dynamic ...
