Abstract:
An integrated circuit voltage regulator includes a transconductor first stage; and a negative impedance cancellation stage, where the negative impedance cancellation stage comprises cross-coupled transistors at outputs of said transconductor first stage, and resistors in the transconductor first stage and the negative impedance cancellation stage introduce zeros in a transfer function, compensating for parasitic poles. The resistors may compensate for parasitic capacitance inherent in transistors. Load transistors may be coupled to outputs of the transconductance first stage. The voltage regulator may be implemented in a Complementary Metal-Oxide-Semiconductor (CMOS) structure, which may be a system-on-chip integrated circuit. The voltage regulator may provide immunity to power supply noise. The negative impedance cancellation stage may include differential input transistors coupled to the cross-coupled transistors.
