An integrable current-tunable sinusoidal quadrature oscillator is presented. A current-tunable all-pass filter is used as the frequency-selective network. The implementation is fullybalanced so as to enable accurate quadrature signals with symmetry. The oscillation frequency is currenttunable over a wide-freqency sweep range of approximately three orders of magnitude. The quadrature signals pos...
