Abstract
In described examples of a ramp circuit, a first terminal of a capacitor is coupled to a ramp terminal and a second capacitor terminal is coupled to a return terminal. A charge source has an input terminal coupled to a supply terminal and a charge output terminal. A resistor has a first terminal coupled to the return terminal. A first switch is coupled between the ramp terminal and a second terminal of the resistor. A second switch is coupled between the charge output terminal and the ramp terminal.
