Simplified Low-Voltage and Low-Power Bipolar OpAmp with Non-linear Class-AB Rail-to-Rail Output Stage
A simplified low-voltage and low-power bipolar OpAmp is presented using a non-linear class-AB control and rail-to-rail output stage. The circuit operates on supply voltages down to 1V. This OpAmp is intended for use as an on-chip building block and contains only 38 transistors. The OpAmp is successsfully realised in a semi-custom process with lateral PNPs. The measured 0dB gain bandwidth is 580kHz. The OpAmp can deliver +1.3mA/¿1.7mA maximum output current, while the quiescent current of the total circuit is only 70¿A.
