Abstract
A circuit includes a first bipolar junction transistor (BJT) including a first base, a first collector, and a first emitter, the first collector connected to a first supply voltage node and a second BJT including a second base, a second collector, and a second emitter, the second collector connected to the first emitter at an output node. The circuit also includes a capacitor including a first capacitor terminal and a second capacitor terminal, the first capacitor terminal connected to the second emitter of the second BJT and the second capacitor terminal connected to a second supply voltage node. A current source device is also included that is connected in parallel with the capacitor.
