ELECTRONICALLY TUNABLE LC HIGH PASS LADDER FILTER USING OTRA

This paper presents Operational trans-resistance (OTRA) based electronically tunable high pass L-C based ladder filter. The proposed high pass filter is designed by following a systematic approach using leap frog simulation for ladder filters. The cut-off frequency of the proposed filter can be varied with the application of appropriate voltages to the gate of MOSFETs hence making the design electronically tunable. Therefore, it can be used for RF applications at 455kHz and 1MHz (intermediate frequencies for RF applications). Performance of the proposed circuit is verified through SPICE simulations employing a 0.5m MOSIS AGILENT CMOS realization of OTRA.
