Abstract :
A decoupling circuit using an op-amp is proposed to suppress noise coupling in mixed-signal SoCs. It solves the parasitic inductance problem of on-chip capacitor decoupling. A 0.13μm CMOS test chip shows that substrate noise at 40MHz to 1GHz is suppressed by each circuit operating at 3.3mA and 1V. These circuits reduce noise down to 68% at 200MHz.
