Input bias current is a usually overlooked amplifier parameter that can have a significant effect on an amplifier circuit’s output accuracy. Sometimes the effect is small enough to be ignored, but ...
The Microchip’s MCP6421 operational amplifiers (op amps) has low input bias current (1 pA, typical) and rail-to-rail input and output operation. This family is unity gain stable and has a gain ...
An N-channel JFET has a low bias current when its gate is biased negative to the source. However, this requires either that the gate voltage be biased negative with respect to the source voltage or ...
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 ...
Bob Pease got an e-mail in 2006 from an engineer who was having trouble with an integrator circuit. Amplifiers are often called op amps because they were originally used as operational amplifiers.
Over on his YouTube channel [Aaron Danner] explains biasing transistors with current sources in the 29th video of his Transistors Series. In this video, he shows how to replace a bias resistor (and ...
