Abstract: Two grounded voltage controlled resistors operating in saturation region are proposed. The first proposed grounded voltage controlled resistor employs 8 metal-oxide semiconductor (MOS) transistors and the second one uses 10 MOS transistors. The proposed GVCRs having only one control voltage do not need any bias currents and voltages constructed with extra elements. One of the main properties of the proposed tunable resistors is to operate at higher frequencies. The first proposed tunable resistor needs a matching condition between power supply voltages while the second does not require such a matching constraint. A video filter example for the proposed tunable resistors is also given. A number of simulations with SPICE simulation program are included in order to exhibit effectiveness, performance and workability of the proposed tunable resistors.
