Beschreibung
Zusammenfassung:In this paper, low voltage CMOS transconductors using the series composite transistors are presented. The minimum input voltage of the designed circuits is V/sub Tn/, which is suitable for low supply voltage. The designed circuits have been simulated by HSPICE using 0.25 /spl mu/m n-well CMOS process. Simulation results show that THD is less than 1.2% for the differential input signal of up to 1.5V/sub p-p/ when the input signal frequency is 10 MHz.
