In this paper, a new switched opamp is presented in order to improve the operation of auto-zeroed switched capacitor circuit. This approach results in a considerable reduction in power consumption and a moderate speed improvement. Based on the above improvement, a second-order band-pass filter with a center frequency of 833 kHz and quality factor of 8 is realized and compared with previous works. The proposed switched opamp is also utilized in the structure of a novel z to -z2 block for the design of pseudo two-path band-pass filters. A second-order pseudo two-path band-pass filter with the same specification of the previous work is designed, simulated, and compared.
