Abstract
A voltage converter for converting an analog input signal into a digital signal is provided. The pulse width of the digital signal is relative to the voltage level of the analog input signal. The voltage converter includes a comparator and a feedback module. After comparing the analog input signal and an analog feedback signal, the comparator generates the digital signal. When the analog input signal is higher than the analog feedback signal, the digital signal has a first voltage level. When the analog input signal is lower than the analog feedback signal, the digital signal has a second voltage level, which is different from the first voltage level. Based on the digital signal, the feedback module adjusts the analog feedback signal toward the analog input signal.
