| Tóm tắt: | This paper presents a systematic synthesis procedure for generating universal voltagemode biquadratic filters based on the nodal admittance matrix expansion. The obtained
eight equivalent circuits can realize all five standard filter functions namely lowpass,
bandpass, highpass, notch and allpass employing only two active elements. The obtained
circuits offer the following advantages: five inputs and two outputs, simple circuit
configuration, orthogonal controllability between pole frequency and quality factor, and
low active and passive sensitivities. The workability of some synthesized filters is verified
by HSPICE simulations to demonstrate the usefulness of the proposed method. |
