Abstract
A circuit design technique is presented which is able to suppress large EMI (electromagnetic interference) radiated by the power supply lines. Implemented in AMIS 0.35-mum I3T80 process, the proposed circuit can suppress maximum 35-dB di/dt noise at high frequency with only 30-muA quiescent current and 100 pF output capacitance fully integrated on chip. Measurement results show that the developed circuit techniques significantly improve the power supply integrity.
