摘要：
A new voltage-variable inductor (VVI)-L realization scheme using composite Current Feedback Amplifier (CFA) and Multiplication Mode Current Conveyor (MMCC) active building block (ABB) is presented. Subsequently a LC-type voltage controlled quadrature oscillator (VCQO) with linear tuning law is derived by replacing the CFA by another MMCC. Experimental results based on PSPICE simulation and hardware circuitry for a linear tuning range of oscillation frequency (f(o)) similar to 9.3 MHz with satisfactory phase-noise figure on the wave generation, had been verified. Effects of the ABB nonidealities are shown to be insignificant.
