Abstract
A method and apparatus (e.g. circuitry) provide high-speed charge-coupled CMOS TDI imaging based on the parallel readout operation of multiple TDI stages. A plurality (N) of output registers are reset and precharged globally in parallel ready to take charge transferred from the same number (N) of the TDI pixel registers. Each of the signal charges at respective output registers is converted to a signal voltage in parallel. Each of the analog signal voltages is then converted to a digital value in parallel by each of the number of the ADCs. The AD conversion is also performed in parallel while the next N number of the TDI registers is processed. The N output registers are linked to receive the charges from a beginning of the registers along to an end. Converting the respective signal voltages is performed by S/H capacitor array circuitry in a ping-pong fashion using CDS voltages.
