Design of a new type self-biased current mode loop filter;

It uses the traditional principle of bandgap reference together with the self-bias structure and startup circuit to get the stable voltage output and good temperature coefficient.

This paper introduces a low supply voltage band -gap reference circuit which used a self-bias cascode current mirror.

Years of teaching practice prove that students can easily understand self-bias effect caused by emitter,while a fair proportion of the students cannot understand self-bias effect caused by base electrode.

A Low - Power adaptive biasing circuit is introduced to reduce the stand - by power dissipation without affection the transient performance by providing a very small biasing current, whose task is the compensation of the threshold voltages of the transistors.

It is implemented in two common-emitter stages with adaptive bias circuit which is used to improve linearity.

To avoid PVT variations in traditional voltage-bias linear power amplifier,a PVT-insensitive current-bias linear power amplifier is described with novel low-coupling adaptive bias circuit and an improved Load-Pull simulation method.
