Multi-channel precision synchronous voltage-to-frequency converter |
摘要 |
A multi-channel synchronous voltage-to-frequency converter (SVFC) realized in an integrated semiconductor circuit. The multi-channel SVFC having an operational amplifier adapted to receive an analog data signal to be converted and a reset signal, the operational amplifier integrating the sum of the analog signal and the reset signal and generating an output signal as a function of the integrated sum; a comparator coupled to receive the integrated sum and a reference level signal, the comparator outputting a logic level signal as a function of the received reference level signal; a digital logic circuit in response to an external clock signal, the digital logic circuit receiving the logic level signal and generating a reset control signal and a frequency output pulse as a function of the logic level signal; and a reset source switch receiving the reset control signal and outputting the reset signal.
