1 Charge Pump

The primary use of the charge pump is to supply a constant voltage to the gates of transistor devices contained in analog peripherals, signal and reference circuitry, and to prevent degradation of transistor performance at low operating voltages. By using the charge pump for any of the mentioned applications, it will result in consuming additional current. Ultimately, it is up the reader to decide when to use the charge pump. This section describes how to configure and use the charge pump.
