In this research, a low voltage BiCMOS operational amplifier was built using parasitic bipolar transistors in bulk CMOS technology. Designed and analyzed using PSPICE circuit simulation software, the amplifier achieves a gain bandwidth product of 20.24 MHz with power supply voltages of - 2.5 V. The simulation proved that the BiCMOS amplifier will operate with power supplies as low as - 0.6 V. Using MAGIC VLSI software, a layout of the amplifier was made for eventual fabrication in the MOSIS 2.0 m CMOS process.
