Abstract
PURPOSE:To prevent the occurrence of a folding signal in a switched capacitor filter, by providing a capacitor in the middle of bridge-connected transistors and switching alternately transistors in opposite sides. CONSTITUTION:Bridge-connected transistors (TR) Q11-Q14 are driven by clocks phi3 and phi4 having the half period of clocks phi1 and phi2 which drive a switched capacitor filter and have phases opposite to each other. When the clock phi3 is high-level, TRs Q11 and Q14 are turned on to sample an input signal v1. When the clock phi4 becomes the high level, TRs Q12 and Q13 are turned on, and charge of a capacitor C1 is transferred to a capacitor CB for integration, and the input signal v1 is sampled. Since the sampling frequency can be set to a high frequency, the capacity of the capacitor CB is reduced, and the number of capacitors is restrained to one.
