  • Biquad block with switched capacitors without continuous feedback loop and with no sensitivity compared with the gain of operational amplifiers and the ratio of the capacitances
    Patent number: 4841263
    Abstract: The biquad block or cell comprises two operational amplifiers OA1, OA2, eight capacitors C1-C8 and switches comprises switches of reference o and switches of reference e controlled by a clock signal H. The biquad block has six connections P1-P6 and can be used as low-pass, band-pass or high-pass filters, as a function of the connections chosen for the input and output of the signal to be filtered. Switches 46 to 52 make it possible to select one from among several configurations for each filtering function. The different configurations are distinguished by their sensitivities to the gain of the operational amplifiers and to the capacitance ratio. Application to the filtering of signals in the video range (a few megahertz).
