Abstract:
1. A circuit, comprising: a first capacitor having first and second terminals; a second capacitor having first and second terminals, the first terminal of the second capacitor coupled to the second terminal of the first capacitor; a first transistor coupled across the first capacitor; a second transistor coupled to the first transistor and across the second capacitor, wherein the first and second transistors are adapted to provide a bleed current to the first and second capacitors to balance a leakage current imbalance in the first and second capacitors; and a resistor divider network coupled to generate at least a first input reference and a second input reference, the first input reference is greater than the second input reference, the first and second input references coupled to respective control terminals of the second and first transistors, respectively.
