A new polyphase current-mode filter using programmable-gain current-controlled current-conveyor

A novel polyphase current-mode filter suitable for CMOS integrated circuit implementation is presented. The circuit uses two programmable-gain current-controlled current-conveyors and two grounded capacitors. The proposed circuit can be operated from a low power supply voltage (±1.25V) and its parameters enjoy low active- and passive-sensitivity. Simulation results using CMOS programmable gain CCCII are included.
