摘要: A ramp generator for use in readout circuitry includes an integrator coupled to receive a input reference signal generate be received by analog digital converter. power supply compensation circuit that is the delay including variable resistor and filter capacitor signal. The tuned match ripple from bitline output. capacitive voltage divider first second are provide capacitance ratio matches coupling
