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 ...
The circuit in Figure 1 sinks a constant current (ICE3) through Q3’s collector and emitter. This design is balanced so changes in Q3’s base-emitter voltage (VBE) don’t affect the current sink’s ...
