Japanese Patent JPS611792
Kind Code:
B2
Abstract:
PURPOSE:To obtain a switched capacitor type integral network having the reduced occurrnce of the folded noise, by having a complementary action of the switched capacitors of the same constitution. CONSTITUTION:The input signal is applied to an input terminal 1 and then to the 1st and 2nd switched capacitor circuits 4-1 and 4-2 which have the same constitution and perform a complementary action. For each switch 6, a switch 6-4 is on with switches 6-3 and 6-4 turned off when a switch 6-1 is on, and a switch 6-4 is off with switches 6-3 and 6-4 turned off when the switch 6-1 is off respectively. In other words, the switches 6 are controlled to perform a complementary action so that one of the circuits 4-1 and 4-2 has a discharging action when the other is carrying out a charging action.
