Filter Configuration

A novel current-mode multifunction inverse filter configuration using single current feedback amplifier (CFA) is presented. The proposed filter employs only one CFA and few passive components. The proposed circuit realizes inverse lowpass, inverse bandpass and inverse highpass filter functions with proper admittances. The characteristics of proposed multifunction inverse filter configuration are- current-mode realization; use of only one CFA; use of grounded passive components except one virtually grounded and realizing all three basic inverse filters. The proposed current-mode inverse filter circuit has been tested by TINA PRO simulation program and results justified the theoretical analysis.

Theoretical Results

A new voltage mode Proportional-Integral-Derivative (PID) controller employing Current Differencing Buffered Amplifier (CDBA) is presented. The proposed PID controller employs a canonical number of capacitors without requiring any passive components matching conditions. The element values are expressed in terms of PID parameters. Workability of the proposed controller is demonstrated through SPICE simulations for which CDBA is realized using Current Feedback Amplifier (CFA). The simulation results are found in close agreement with the theoretical results.

Alternative Choice

Simulation of inductors has been a very popular area of analog circuit research and the alternative choice for realizing inductor-based circuits in integrated circuits. In this paper, lossless, grounded and floating inductor topologies using current-controlled-current-feedback amplifier (CC-CFA) with single grounded capacitor are presented. The proposed topologies can be tuned electronically by changing the biasing current of the CC-CFA. Two topologies for grounded inductor simulator employ two CC-CFA and one grounded capacitor. One topology for floating inductor simulator employs three CC-CFA and one grounded capacitor. The performance of the grounded and floating inductor simulators are demonstrated on resonant circuits. The theoretical analysis is verified by PSPICE simulation results.
