ABSTRACT:
An input MOS transistor receives an input voltage and produces a current corresponding to the input voltage. A charge/discharge circuit charges a capacitor alternately in two different directions by the output current of the transistor. A select circuit alternately selects and produces one of the potentials at either of the electrodes of the capacitor. A single two-input comparator compares a reference potential with a potential of the output signal of the select circuit. The select circuit produces a signal corresponding to the comparison result. The select circuit allows the output signal of the comparator to be transmitted alternately to the set input terminal and the reset input terminal of a flip-flop. The flip-flop is set and reset by the output signal of the switch means to produce an oscillating signal. According to a change in the level of the oscillating signal, the charge/discharge circuit switches the charging direction of the capacitor. According to a change in the voltage level of the output signal of the flip-flop, the select circuit selects the potential which is higher in absolute value than the other. According to a change in the voltage level of this output signal, the switch circuit directs the output signal of the comparator to one of the set and reset input terminals of the flip-flop.
