This paper proposes a technique to reduce the capacitance spread in switched-capacitor (SC) filters. The proposed technique is based on a simple charge distribution and partial charge transfer which is applicable to various integrator topologies. An implementation example on an existing integrator topology and a design example of a 2nd-order SC low-pass filter are given to demonstrate the performance of the proposed technique. A design example of an SC filter show that the filter designed using the proposed technique has an approximately 23% less total capacitance than the one of SC low-pass filter with conventional capacitance spread reduction technique.

“…There are various filter implementations such as passive RC filters, active RC filters [1][2][3][4], Gm-C filters [5][6][7][8][9][10][11][12][13][14], and switched-capacitor filters [15][16][17][18][19][20]. Among those well known filter topologies, switched-capacitor filters have been noticed for their low sensitivity to parameter deviation.…”

This paper proposes a technique to reduce capacitance spread in switched-capacitor filters. The proposed technique is based on a simple charge distribution and a partial charge transfer techniques, and is applicable to various integrator topologies. Simulation results show that the proposed technique reduces the total capacitance by 70%, which is a significant reduction of filter area. Furthermore, an integrator implemented by the proposed technique is found to be insensitive to parasitic capacitances.
