  • Quadrature signal generator with spike-less prescalar circuit
    Patent number: 5808499
    Abstract: Self-oscillation of a prescalar circuit is avoided by including offset generators on the inputs of the prescalar circuit. This ensures that when the transistors in one differential pair in the prescalar circuit transition from ON to OFF, the other differential pair of transistors will not transition. As a result, spikes are prevented in the differential pair that does not have a transition. A quadrature signal generator constructed with such a prescalar circuit provides an accurate output despite weak or non-existent input signals.
