Jaeger/Blalock 7/28/10 Microelectronic Circuit Design, 4E McGraw-Hill 232 -2 Biasing with Electronic Current Sources Differential amplifiers are biased using electronic current sources to stabilize the operating point and increase effective value of REE to improve CMRR Electronic current source has a Q-point current of ISS and an output resistance of RSS as shown. DC model of the electronic current source is a dc current source, ISS while ac model is a resistance RSS . SPICE model includes both ac and dc models.
