Abstract:   (12832 Views)
In this paper a new approach for design of class-AB current-mode square-root domain filters based on the electronically simulated translinear loop principle is presented. FG-MOS transistors that operate in strong inverted saturation region are employed for implementation of translinear loop circuit. The filter achieves immunity to body effect, low circuit complexity, large input dynamic range, and also works in low voltage compared to those reported before. With supply voltage 1.2V a dynamic range of 46dB at 1% THD is achieved. Simulation results by HSPICE confirm the validity of the proposed design technique and show high performance of the filter.
