Abstract
This paper describes switched-capacitor (SC) inductor and Frequency Dependent Negative Resistor (FDNR) which use second generation current conveyor (CC II). In general CC II's used in SC circuits are not always used as CC II and there are phase periods in which CC II behaves as much simpler active device like unity gain buffer (UGB). In this paper, CC II's in SC circuits always behave as CC II to make full use of CC II. Then an SC inductor in which effects of parasitic capacitors can be reduced is proposed. And SC FDNR which uses CC II to get a simple circuit structure is also proposed. Both circuits are controlled by simple two-phase control clock. The spreads of capacitor values are 1. The sum of capacitor values of SC FDNR is 4. This value is the smallest reported value in SC FDNR circuits. Simulation results by SWITCAP and experimental results by discrete components are shown.
