    摘要: 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.

    摘要: A digital-to-analog convertor divides an input digital signal into a least significant bit group and a most significant bit group. The most significant bit group is converted using pulse amplitude modulation and the least significant bit group is converted using pulse width modulation, in which the pulse widths are varied symmetrically about predetermined time points within a conversion period in order to improve the linearity of the pulse width modulation conversion.

    摘要: 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.

    摘要: An integrating digital-to-analog converter circuit includes an operational-amplifier based integrator, a plurality of constant current sources each providing constant current at a respective different level, and a plurality of switches each associated with a respective current source for coupling the same to the integrator. A plurality of digital counters are arranged to hold a predetermined portion of an n-bit digital word loaded therein and to count clock pulses until their contents reach a predetermined count. At those times, a carry pulse is generated in each such digital counter and the associated switch is opened to cut off the associated current source. Such a digital-to-analog converter circuit can convert data words of relatively high bit length without the need for an excessively high frequency clocking signal.
