Abstract
The present invention provides a differential amplifier. The differential amplifier includes first and second inputs and an output. The differential amplifier further includes a lateral bipolar transistor. The lateral bipolar transistor includes a well region that has a base region, an emitter region and first and second collector regions. The first and second collector regions are spaced apart from the emitter. The lateral bipolar transistor also includes a first gate, coupled to the first input, to overlay a space between the emitter region and the first collector region. Furthermore, the lateral bipolar transistor includes a second gate, coupled to the second input, to overlay a space between the emitter region and the second collector region. The differential amplifier further includes first and second load devices coupled to the first and second collector regions.
