| Abstract: | In this letter, we propose RC and LC nonlinear sinusoidal ring oscillator structures which can also generate subsidiary quadrature outputs. A tanh(x) nonlinearity is employed and is explicitly separated from the oscillators' linear building block (a first‐order all‐pass filter). Numerical and spice simulation results are given.
