Abstract
A generator circuit for voltage ramps is provided that includes a differential stage with positive feedback coupled between a first and a second voltage reference and having a first output connected to a control terminal of a first output transistor. The first output transistor is connected at an output terminal of the ramp generator circuit to a capacitive charge to be biased with voltage ramps. The ramp generator circuit also includes a second output transistor parallel connected to the first output transistor and having the control terminal connected to a second output of the differential stage.
