and thus the current that flows between drain and source is proportional to the gate voltage. We have an amplifier. A simple FET radio receiver circuit showing FET biasing. The gate is biased at ...

Because the emitter is grounded, even if sometimes via a resistor, this transistor configuration is referred to as a Common Emitter ... the self-biasing amplifier. Try 330k for R6, and 1k for ...

2). Made on a 0.8-µm CMOS process, the X9470 is crafted to set the bias operating points for class A or AB amplifiers. While the drain current is constant in type A, it's always changing in class ...

An alternative circuit divides down the high common-mode current-shunt voltage, theoretically permitting the 5V-powered amplifier to extract the current measurement over a 20 to 90V APD bias range ...
