Abstract :
This paper discusses the design of a low common mode and offset voltage amplifier for current sensing in power IC applications. The current is sensed through a resistor connected between the source of a power device and ground. The sense amplifier operates with low input voltages, therefore requiring low input offset voltage to minimize the gain error. The amplifier was designed using bipolar and MOSFET components in a 1 μm BiCMOS process technology
