ANALOG/DIGITAL CONVERSION PROCESSING UNIT

摘要

PROBLEM TO BE SOLVED: To provide an analog/digital conversion processing unit that can easily increase number of phases for a polyphase conversion clock and obtain a highly accurate delay. SOLUTION: Data conversion circuits 106 each configured with a clock control circuit 107 consisting of an input amplifier 109 receiving a pulse from a pulse shaping circuit that shapes amplitude and a pulse width of a clock with a prescribed period, of a delay circuit 110 that delays the pulse from the input amplifier 109 to generate a clock for analog/digital conversion, and of an output amplifier 111 that outputs the delayed pulse from the delay circuit 110 and with an analog/digital converter circuit 108 that applies analog/digital conversion to a converted signal supplied through a distribution circuit with a clock for analog/digital conversion supplied from the delay circuit are connected in al way that the clock control circuits 106 are connected in series.
