ABSTRACT:
A CMOS bandgap reference (BGR) voltage generator circuit has a passive resistor T-network of low resistance connected between the inverting and non-inverting inputs of the op-amp in the circuit. The op-amp's output is connected to the gates of three PMOS transistors and the drains of two of the transistors are connected in a looped manner to the input terminals of the op-amp. The T-network is placed between these drains that connect to the op-amp. Becuse of the rules governing abstracts, this abstract should not be used to construe the claims.
