  • Patent number: 8059708
    Abstract: A pulse width (PW) digitizer comprises a current pump, a capacitor, a quantizer, a feedback controller, and a digital filter. The current pump provides a current signal in response to a PW signal. The capacitor obtains a voltage signal in response to the current signal. The quantizer obtains a digital signal in response to the voltage signal. The feedback controller determines a feedback PW signal in response to the digital signal. The feedback PW signal is fed back to the current pump for controlling the current signal converging to a specific value and controlling the digital signal switching between a first code and a second code. The digital filter counts times that the digital signal indicating the first code/the second code and accordingly obtains the PW of the PW signal.
