Abstract
A buffer circuit includes a first capacitor having a first terminal coupled to receive an input signal, a second capacitor having a first terminal coupled to the first terminal of the first capacitor, and a latching portion coupled to a second terminal of the first capacitor and a second terminal of the second capacitor. The latching portion provides an output signal. A first transistor includes a control electrode coupled to receive the output signal, a first current electrode coupled to a first bias voltage supply terminal, and a second current electrode coupled to the second terminal of the second capacitor.
