SQUARE-ROOT-DOMAIN SECOND-ORDER TRANS-ADMITTANCE TYPE UNIVERSAL FILTER DESIGN
Abstract :
In this study, a square-root-domain (SRD) electronically-tunable second-order trans-admittance type filter is proposed. The proposed filter has one voltage input and two current outputs and can simultaneously realize low-pass (LP) and band-pass (BP) responses without any changes in the circuit topology. Additionally, trans-admittance type second-order universal filter that has low-pass, band-pass, high-pass (HP), all-pass (AP) and notch (N) outputs is realized by adding a circuitry. The transfer admittance parameter g0, natural frequency f0 and quality factor Q of the trans-admittance type filter can be electronically tuned by changing DC control current sources. Some time and frequency domain simulations are performed using PSPICE program for the proposed trans-admittance type filters.
