    • An analog delay circuit which includes an analog memory circuit wherein a plurality of memory cells each including a memory capacitor and a selection switch for the memory capacitor are arranged in a matrix includes row switches provided for the individual columns for individually being driven by row selection signals. A same clock signal from a clock generation circuit is supplied commonly to an X direction scanning circuit and a Y direction scanning circuit. The number of stages of registers of the X direction scanning circuit and the number of stages of registers of the Y direction scanning circuit are set so that they have no common divisor other than 1. Consequently, when the memory cells are to be selectively scanned, a same selection condition can be provided to all of the memory cells without relying upon the positions of the memory cells, and the parasitic capacitance connected to a signal write/read terminal is reduced.

    • A peak detector having rise-time enhancement of input signals is comprised of a feedback amplifier including two input terminals and a feedback circuit which interconnects the amplifier output terminal with one of the input terminals; and a peak detecting circuit, including a capacitor, coupled to the other of the amplifier input terminals. The capacitor voltage is applied as an input signal to the feedback amplifier, and abrupt changes in the rise-time portion of the input signals are detected and are used to vary the amplifier feedback so as to enhance the output signal produced by the amplifier during the rise-time portion.

    • When a current charge method is used as a method of detecting capacitance, there poses a problem in which S/N is deteriorated by a dispersion in element characteristics of a cell to be detected and when a voltage charge method is used, since parasitic capacitances of column sense lines are very large and accordingly, there is needed some devise for sampling electric charge charged to the capacitance. There are arranged unit cells having detection electrodes and cell selecting switches connected between the detection electrodes and column sense lines in an array shape, electric charge is charged from detecting circuits to the detection electrodes under constant charge voltage, and thereafter, the column sense lines are imaginarily grounded to thereby detect the capacitances formed between the detection electrodes and the surface of the finger in accordance with recesses and projections of a fingerprint via the column sense lines.
