单片CDCTA-C低功耗电控调谐双模式三阶正交振荡器的设计
Design of Low-Power Electronically Controllable Dual-Mode Third-Order Quadrature Oscillator Using Single CDCTA-C
摘要
Abstract
In order to solve problems of high power consumption and low oscillation frequency in oscillator,this work presents a third-order quadrature oscillator circuit employing CDCTA (Current Differencing Cascaded Transconductance Amplifiers).The proposed structure employing only one CDCTA and three grounded passive capacitors realizes four explicit quadrature current outputs and two quadrature voltage outputs simultaneously.Meanwhile,the circuit power consumption is only 1.8mW,the maximum sensitivities value of only 0.5 and the oscillation frequency of up 10MHz magnitude.Moreover,its oscillation condition and oscillation frequency can be tuned electronically and independently.Results from computer simulation and hardware experiment validated the theoretical analysis of the circuit.关键词
