Fifth-order lowpass sc ladder filter with reduced sensitivity to operational amplifiers finite gain and offset voltage
TU - Sofia
A combined approach for reducing the effects of operational amplifiers finite DC gain and offset voltage in fifth-order lowpass SC ladder filter is proposed. The filter with gain- and offset-compensated integrators and modified capacitance values yields significant improvement in the passband response.
