Abstract
A process monitoring circuit may be used to determine appropriate voltage for integrated circuits including a non-volatile memory. The process monitoring circuit includes a bandgap reference, a clock generator, a negative bias circuit, a temperature insensitive oscillator, a low dropout voltage regulator, a counter, a comparison circuit, and a charge. The process monitoring circuit may also include a pulse width generator. The process monitoring circuit is able to determine the process corner of which a monitored circuit belongs to and generate an output voltage according to the process corner of the monitored circuit.
