摘要： A DC motor is supplied, from a motor driver, with a brake voltage constituted by a forward drive voltage, a reverse drive voltage, and a stop voltage of a zero potential level. An operational current of the motor driver is supplied to a low-pass filter whose output is supplied to first and second sample and hold (S/H) circuits. The first S/H circuit performs its sampling operation after a minute period of time in which the brake voltage goes through a polarity inversion from the reverse drive voltage to the forward drive voltage. The second S/H circuit performs its sampling operation after a minute period of time in which the voltage applied is changed from the forward drive voltage to the reverse drive voltage. The outputs or sampled values of both S/H circuits are compared with each other by a comparator. When the sampled values equal each other, i.e., when the number of rotations of the motor becomes zero, the comparator outputs a coincidence pulse. This pulse is supplied to a stop detector. When detecting this coincidence pulse a predetermined number of times in a row, the stop detector determines that the number of rotations of the motor has become zero.

摘要： A semiconductor integrated circuit comprises a differential pair of transistors, a pair of constant current source transistors, an emitter resistor connected between the emitters of the differential transistors, and a load resistor coupled to the collector of one of the differential transistors. Each of the differential transistors and constant current source transistors is a vertical PNP transistor. In the semiconductor integrated circuit, therefore, each vertical PNP transistor has its collector coupled with a parasitic diode having a relatively large junction capacitance. The parasitic diodes are reversely biased when the circuit is operative. In order to prevent the frequency characteristic from being deteriorated due to the junction capacitance of the parasitic diodes, a resistor circuit, which forms a differentiating circuit together with the emitter resistor and the parasitic diodes, is connected between the cathodes of these diodes and a power source, whereby the differentiating time constant of this differentiating circuit is so adjusted as to become substantially equal to the integrating time constant of an integrating circuit including the load resistor and the parasitic diode.
