In the fourth chapter , a fourth - order chebyshev low - pass filter employs new low voltage , highly linear , wide inputting range transconductor is proposed , then we presents a new circuit to tune gm value of transconductor accurately , which employs a new switched - capacitor circuit to change the bias current of transconductor , a third order elliptical function low - pass filter with accurate tunable frequency has been designed using transconductor that is not only with voltage common - mode negative feedback , but also with varying bias - triode transistors which can improve the linearity of this circuit 第四章:提出了一种新的低电压、高线性度、宽输入范围跨导,并由此设计实现了四阶切比雪夫( chebyshev )低通滤波器,接着提出了一种宽输入范围且具有电压共模负反馈的全差分跨导,并采用一种新的开关电容电路实现跨导值gm精确可调,从而可以设计得到高性能具有精确截止频率的跨导-电容三阶椭圆函数滤波器。
