    摘要： A filter circuit that consumes very little electric power. The active filter is a linear inverter constructed by 1) an inverting amplifying portion composed of an odd number of MOS inverters serially connected, 2) a grounded capacitance connected between an output of the inverting amplifying portion and ground, 3) a balancing resistance having a pair of resistances for connecting an output of one of the MOS inverters, other than the last MOS inverter, to the supply voltage and the ground, respectively, and 4) a feedback impedance for connecting the output and input of the inverting amplifying portion. A coupling capacitance is connected to the input of the linear inverter and a plurality of filter circuits are connected to an input of the coupling capacitance.

    摘要： An amplifier circuit has a wide frequency range which is broader than the frequency range expected from its circuit parameters. The amplifier circuit comprises a plurality of unit amplifier circuits connected in parallel. Each unit amplifier circuit contains an odd number of inverters serially connected from the first stage to the last stage, an input capacitance connected to the input terminal of the first stage, and a feedback capacitance connecting the output terminal of the inverter of the last stage to the input terminal of the inverter of the first stage. Thus, the amplifier circuit operates in a wide frequency range with little decrease in gain at high frequencies.

    摘要： A scalar circuit includes serially connected inverters connected to one another via a plurality of connecting lines. A plurality of input lines are provided to the input of a first inverter in the serially connected inverters. A plurality of feedback lines are provided between the input and output of each inverter. A capacitance and a switch is provided in each connecting line, input line and feedback line. The switch connects a terminal of the capacitance to ground while simultaneously disconnecting the ends of that line from one another. The switches are cooperatively actuated so that the effective composite capacitance in the feedback lines and the connecting lines are substantially equal. In addition, the composite capacitance of in the input lines and the connecting lines are substantially equal.
