Abstract
A circuit includes a comparator having first and second comparator inputs and a comparator output. A discharge switch is coupled between the first comparator input and a ground terminal. A capacitor has first and second capacitor terminals, in which the first capacitor terminal is coupled to the first comparator input. A delay correction circuit includes a sample-hold circuit coupled to the first capacitor terminal and the second capacitor terminal. An amplifier has a first amplifier input coupled to a hold output of the sample-hold circuit and a second amplifier input coupled to the second comparator input. A variable resistor is coupled between the second capacitor terminal and the ground terminal, and has a control input coupled to the amplifier output.
