摘要： A system and method for minimizing non-linearity errors induced in output drive voltage of a transmitter circuit due to on-chip process, voltage, and temperature (PVT) variations. The system including an oscillator for converting an input reference bias voltage into a clock output signal, where the input reference bias voltage varies in response to PVT variations. Also included is a counter for counting the clock output signal and generating a count value corresponding to the clock output of the oscillator. A comparison module operatively coupled to the counter compares the count value with a pre-simulated count value to generate an error signal. Based on the error signal generated by the comparison module, a correction logic adjusts an output drive signal of the transmitter circuit making it immune to PVT variations.

摘要： A single photon detection system and method are disclosed which have a control block for helping to monitor and optimize performance, especially at high detection rates. The system is based on photon detectors constructed with avalanche photodiodes (APD) gated in time to operate in the Geiger mode. An electrical reference frequency is generated which is subtracted from the APD output in order to better isolate the breakdown event. The resulting signal is sampled and analyzed to allow the control unit to optimize the magnitude and phase of the electrical reference frequency. The control unit may also change the gate pulse shape and phase, including by the use of a digital-to-analog converter. The gate pulse can be shifted off an input optical pulse so as to estimate dark count rate, or shifted to measure a reference input signal to estimate detection efficiency.

摘要： A photo element includes a capacitor, a switch thin film transistor (TFT), a charge thin film transistor, and a photo thin film transistor. A voltage is charged to the capacitor through the charge TFT, and the output voltage of the capacitor is read through the readout line. The photo-induced current will affect the output voltage of the capacitor; therefore it is employed to determine whether the photo element is touched. Later, a reverse-biased voltage is applied to the photo TFT, such that the threshold voltage and sensitivity of the photo TFT can be maintained.

摘要： A resolution switch circuit for an image sensor uses a control unit to control a plurality of image gathering units to generate and store image signals. A resolution control unit controls a plurality of shift registers through the resolution control signals so that the shift registers control the image gathering units to output image signals. The signal combining unit is used to combine the image signals output from the image gathering units to achieve resolution change. Since the resolution switch circuit for the image sensor according to invention does not require additional resolution switch wiring, the affect of noise can be avoided and cost of the circuits can be reduced. The transmission of the image signals in the form of charges prevents any signal distortion due to resistance of wiring during transmission.
