Design and simulation of ICCII-based analog circuits

In this thesis, negative-type inverting second-generation current conveyor (ICCII-)-based circuits are designed. The first of these circuits is a current-mode universal filter. This circuit includes three ICCII-s, two grounded capacitors, two grounded resistors, and one floating resistor. The circuit has three input currents and two output currents. With appropriate selection of three input currents, lowpass, high-pass, band-pass, all-pass and notch filter output currents can be obtained. The second circuit in this thesis is a four-phase oscillator. Similarly, this circuit consists of three ICCII-s, two grounded capacitors, two grounded resistors, and one floating resistor. If the relevant oscillation condition is met, there are four voltage outputs with a phase difference of 90o. Also, there is an additional current output. Simulations of the circuits are made through the SPICE program. Further, 0.13 μm IBM CMOS technology parameters are used for the MOS transistors in the internal structure of the ICCII-s.
