In this thesis, a number of simulator circuits synthesizing capacitors and inductors have been discussed. The programmable feature of the operational transconductance amplifiers (OTAs) has been exploited to advantage to make the simulator circuits voltage/current controlled and consequently controllable by the output of a digital to analog converter (DAC). This results in digitally programmable tuned circuits. The temperature sensitivity of the OTAs has been converted to make the overall circuit temperature-independent (independent of the usd\rm V\sb{T}usd term), resulting in Digitally Programmable Temperature-Independent Tuned (DiPTIT) circuits. The stability of some of these circuits has been discussed to show how non-idealities of active elements play an important role in determining the performance of such circuits.
