ABSTRACT:
A reference voltage generator that may be useful in analog-to-digital converter (ADC) circuits includes compensation for errors such as from non-ideal considerations such as semiconductor processing variations, mismatch errors, temperature gradients, and parasitic effects. The compensation method employs a correction current that is provided to the reference voltage generator to adjust the delay time and stability of the resulting reference voltage or voltages.
