Abstract :
A novel versatile CMOS voltage to current converter is presented. The conversion transistors operate in the triode region. The linearity is high (total harmonic distortion <0.4% for 6 Vpp input signals on a breadboard). The transconductance can be tuned over a wide range (factor 25 on breadboard, factor 100 expected on chip). The input voltages are not restricted to a common mode level. The transconductor has floating inputs resulting in a good common mode rejection ratio
