Novel Current Mode First-Order Filter and Oscillator

A novel current mode first-order universal filter is developed using the dual X second generation multi-output current conveyor (DX-MOCCII), capacitors and resistors to produce current mode low pass, high pass and all pass responses. The filter’s sensitivity is quite low. In the paper being given, a new sinusoidal oscillator based on DX-MOCCII is introduced. The oscillator’s frequency can be adjusted without affecting the circuit structure. Using PSPICE simulator and parameters for a 0.25 µm CMOS (TSMC) model, the block was built. The effectiveness of the filter is assessed using the Cadence OrCAD simulator. Results from simulations back up the theory.
