Abstract
In this paper, a new current-mode quadrature oscillator (CMQO) is proposed
using two grounded capacitors and two resistors along with two multi-output dual-X second
generation current conveyors (MO-DXCCII). The proposed circuit provides three current
outputs simultaneously with high output impedances. The circuit of proposed quadrature
oscillator also enjoys the low active and passive sensitivities. The new circuit is suited for
high frequency and low operating voltage operation also. The proposed circuit is also made
resistorless by using MOS based active resistors. HSPICE simulation results are given to
confirm the theory.
