摘要

本文提出了一种新的三阶正交振荡器拓扑结构，该拓扑结构采用了一种新的有源元件——电压差分缓冲放大器(VDBA)。所提出的QO拓扑是使用无损和有损积分器的融合来实现的，这些积分器在时间上产生等间隔的正弦振荡，相移为90度。通过使用0.35µm TMSC CMOS技术的PSPICE模拟，验证了所提出的QO的功能。所提出的QO的总谐波失真(THD)在很宽的频率范围内被观察到相当低。

Voltage differencing buffered amplifier based quadrature oscillator

In this paper, a new topology for a third order quadrature oscillator (QO) using a new active element, voltage differencing buffered amplifier (VDBA) is proposed. The proposed QO topology is implemented using a meld of lossless and lossy integrators that produce sinusoidal oscillations equally spaced in time with phase shift of 90 degrees. The functionality of the proposed QO is verified with the help of PSPICE simulations using 0.35µm TMSC CMOS technology. The total harmonic distortion (THD) of the proposed QO is observed to be quite low for a wide range of frequencies.
