A novel polyphase current-mode filter filter in [16] uses floating capacitors which limits suitable for CMOS integrated circuit implementation is signal frequency operation. presented. The circuit uses two digitally-programmable current-controlled current-conveyors, MOSFETs, and Recently, a current-controlled current-conveyor based two grounded capacitors. The proposed circuit can be realization is presented in [18] which exhibit electronic operated from a low power supply voltage (+1.5V) and its parameters enjoy low active-and passive-sensitivity. tuning for filters parameters. However, available Simulation results using CMOS CCCII are included, tuning range and linearity are limited due to their main dependency on the transistor's transconductance. The Key-Words: -Current-mode, Polyphase filter major intention of this paper is, therefore, to present a new current-mode realization for a first-order
