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
