can someone suggest me some scheme to implement in a big circuit which requires lot of bias voltages that can be generated from one main bias source which is independent with temperature adn variations????
Re: bias circuit scheme IC containing number of bias voltage
i would suggest that you have biasing current rather than biasing voltages.
Use a simple constant-gm circuit to generate biasing currents.
take these current anywhere in the chip and generate the biasing voltages locally.
Global biasing is always through current and local biasing is through voltage
