Abstract
Deterministic asymmetry in a random number generator can be mitigated by a circuit that includes a first inverter, a second inverter, a first capacitor, a second capacitor, a first switch, and a second switch. The first inverter can include a first input terminal and a first output terminal. The first inverter can have a first inverter threshold voltage. The second inverter can include a second input terminal and a second output terminal. The second inverter can have a second inverter threshold voltage. The first capacitor can be conductively coupled between the first output terminal and the second output terminal. The second capacitor can be conductively coupled between the second output terminal and the first input terminal. The first switch can be conductively coupled between the first input terminal and the first output terminal. The second switch can be conductively coupled between the second input terminal and the second output terminal.
