    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.
