摘要:
Fast settling circuits and methods designed to align input signal amplitude level and to remove DC offset voltages with minimal loss of low frequency signal in receiving analog circuits are disclosed. With the key innovative circuits and methods for signal peak alignment, the disclosed circuits and methods achieve fast settling without significant attenuation of the input signal. Peak aligning circuits and methods can be implemented along with conventional RC AC coupling circuits. In applying the aligning circuits and methods to differential signal pair, DC offsets can be easily removed.
