  ABSTRACT: In this paper, a new voltage-mode (VM), all-pass filter utilizing two second-generation current conveyors and tow differential difference current conveyors (DDCCs) is proposed. This filter uses a number of passive elements grounded capacitor. This structure of filter is used to realize a quadrature oscillator. The proposed circuits employ tow optimized differential difference translinear second generation current conveyers (DDCCII). These structures are simulated using the spice simulation in the ADS software and CMOS 0.18 μm process of TSMC technology to confirm the theory. The pole frequency can be tuned in the range of [11.6 - 39.6 MHz] by a simple variation of a DC current.
