Abstract :
This paper proposes a noise suppression method using the combination of a passive guard ring and an active guard band circuit. The proposed active guard band circuit has a better PSRR (power supply rejection ratio) performance than the conventional one. A noise suppression performance of 60 dB and PSRR improvement of 50 dB are achieved by the proposed circuit.
