Abstract :
In this research presents a dual-mode quadrature oscillator with a minimal component count. The design employs
a single Voltage Differencing Differential Voltage Current Conveyor (VD-DVCC), along with two grounded capacitors and
two grounded resistors. The oscillator simultaneously provides both current and voltage outputs. Importantly, the frequency
of oscillation (FO) and the condition of oscillation (CO) can be adjusted independently. The circuit is validated through
simulation at a designed frequency of 2.6971 MHz using 0.18 μm CMOS technology in Cadence design software, operating
with a supply voltage of ±0.9 V.
