Abstract

PURPOSE:To eliminate the unstable factors due to the through rate etc. of an amplifier and to ensure a stable rotating motion, by cascading the sample holding circuits and giving different working timings to an anglog switch element of each sample holding circuit. CONSTITUTION:An analog switch element AS1 is closed for an on-period during which a sensor 2 is sampled to a capacitor C1. While the element AS1 is opened for an off-period during which the sensor 2 is not sampled, and the capacity of the capacitor C1 is held. Then the output D of the C1 is once received by high input and low output impedance element 4 such as a voltage follower, a C-MOS gate, etc. and then made pass through a sample holding circuit consisting of the AS2 and C2. In this case, the timing A' of the on-time of the AS2 is set different from the timing A of the AS1. Thus the signal can be utilized at the off-time of the sample holding circuit of the preceding stage.
