Abstract
A circuit for correcting time encoder errors including a time encoder having a time encoder input, a time encoder output, and a current summing point, and a pulse width modifier coupled to the time encoder output, the pulse width modifier having a current output coupled to the current summing point, and having a corrected output. The pulse width modifier is configured to calibrate duty cycle errors and nonlinearity errors on the time encoder output, to correct the duty cycle errors and the nonlinearity errors on the time encoder output, and to output the corrected output.
