Abstract
A low noise operational amplifier using lateral PNP bipolar transistors has been fabricated in a 1.2 μm digital CMOS process. Total circuit area is 0.211 mm2. The amplifier functions with power supply voltages of ±0.5 V, achieves a GBW product >400 kHz, requires a low quiescent current of 70 μA, and generates En =39 nV/√(Hz) at 10 Hz
