In this work, we present
a current-mode and voltage-mode quadrature oscillator circuit using a voltage
differencing buffered amplifier (VDBA), two grounded capacitors, and a grounded
resistor. The oscillation condition and frequency are orthogonally (or
independently) controllable. The current-mode and voltage-mode quadrature
signals can be simultaneously obtained from the proposed circuit. The use of
only grounded capacitors and resistors makes the proposed circuits ideal for
integrated circuit implementation. The quadrature oscillator is simulated with
SPICE simulation program using 0.35-µm technology parameters.
