| Popis: |
This paper proposes the design of a current-mode resonator with complex coefficients based on fully-balanced operational transconductance amplifiers (FBOTAs) and grounded capacitors. The proposed current-mode resonator can be used in a quadrature /spl Delta//spl Sigma/ modulation for digital radio or can be employed as a foundation to realize high-order complex filters with in cascade or leapfrog for wireless local area network (LAN) applications. For realizing the current-mode resonator herein, only two grounded capacitors as passive elements are required. Thus, the proposed current-mode resonator is suitable for the integrated circuit realization. Chip design and measured results are presented to verify the theoretical analysis. |
