A systematic synthesis method to generate transconductance filters using nodal admittance matrix (NAM) expansion is proposed. The obtained circuits with two input voltage terminals and three output currents employing only two grounded capacitors and three resistors can be used to realize the transconductance-mode universal filter. The synthesized filters enjoy the properties of orthogonal controllability...
A systematic method for synthesizing voltage-mode high-Q biquadratic notch filters is proposed. The proposed approach is based on the nodal admittance matrix expansion method using nullor-mirror pathological elements. The obtained circuits require no component-matching constraints and present low active and passive sensitivities. The Q factor of the derived filters can be adjusted without changing...
