چکیده
We show that the operational transconductance amplifier (OTA), as the active element in basic bnilding blocks, can be efficiently used for programmable nonlinear continuous-time function synthesis. Two efficient nonlinear function synthesis approaches are presented. The first approach is a ratiossaf approximation and tbe second is a piecewise.linear approach. Test circuits have been fabricated using a 3-pm p-well CMOS process. The flexibility of the designed and tested circuits was confirmed.
