A 3.3 V charge-mixer device in a 0.35 μm CMOS process detects the intensity and phase of a modulated signal. A two PMOS pair is used as charge-mixer to exploit the interface-trap charge pump phenomenon. Using clocking between accumulation and inversion, the two transistors perform a voltage-to-charge conversion of the input signal and transfer this charge to the two outputs synchronously to the applied signal.

Abstract
A 3.3 V charge-mixer device in a 0.35 μm CMOS process detects the intensity and phase of a modulated signal. A two PMOS pair is used as charge-mixer to exploit the interface-trap charge pump phenomenon. Using clocking between accumulation and inversion, the two transistors perform a voltage-to-charge conversion of the input signal and transfer this charge to the two outputs synchronously to the applied signal.File in questo prodotto:
