Abstract

An on-chip differential-amplifier-based voltage down converter (VDC) is proposed. Employing a reference voltage generator, which operates in moderate inversion region, the architecture of the proposed VDC is simple and can be fabricated by conventional CMOS technology. VDC converts 3.3V to lower voltage so that the internal circuits of VLSI are used. In this paper, 1.8V is used as an experiment vehicle. The output voltage (V_out) of the VDC is stabilized within plusmn3.8mV for load current varying from 0 to 100mA and within plusmn0.75% for plusmn10% variation of external supply voltage. The temperature dependency of V_out is only 0.329mV/degC
