Parasitic-tolerant components simulation type switched-capacitor filters using unity-gain buffers

Novel switched-capacitor transconductance elements that are free from resistive effects due to parasitic capacitances are used to realize the filters. The absence of resistive parasitics lowers the overall parasitic sensitivity of such filters. The remaining small deviations in the response can be overcome by simple predistortion. Computer simulation on a sixth-order bandpass filter is presented. >
