Abstract :
Though the current-mode odd-nth-order operational transconductance amplifier and capacitor (OTA-C) elliptic filter structure with the minimum number of active and passive components was presented recently, yet none of its counterpart, the voltage-mode ones, have been reported. After a new analytical synthesis method, namely, an innovative algebraic decomposition of a complex nth-order transfer function into n simple and feasible equations, the voltage-mode odd-nth-order OTA-C elliptic filter structure with the minimum number of components is proposed in this paper. The Hspice simulation with 0.35 mum process for a voltage-mode third-order OTA-C elliptic low-pass filter, employing only four OTAs and three grounded capacitors, validates not only precise filtering parameters but low sensitivity and low power consumption performances.
