Abstract :
In this paper, a novel low-voltage, highly linear and tunable triode transconductor is introduced. The proposed transconductor with new structure is based on constant drain- source voltage method to operate at low-voltage. The proposed transconductor achieves wide linear input range up to 1.5 V at 1.8 V supply voltage and the total harmonic distortion is -62 dB at 0.7 Vpp. The design uses TSMC 0.18 mum CMOS technology and supply voltage as low as 1.6V. Moreover, it possesses large transconductance tuning range from 200 muS to 880 muS and also keeps the wide linear input range.
