Latest Patents
Wismar's latest patents include a "Method and apparatus for implementing a quadrature VCO based on standard cells." This invention focuses on a Quadrature Voltage Controlled Oscillator (Quad VCO) that generates two high-frequency output signals that oscillate with a mutual phase offset of about 90 degrees. The digital cells used in this invention consist of standard flip-flop circuits and logic gates, while the delay cells provide a time-delayed version of the input signal, controlled by a voltage analog signal.
Another significant patent is the "Test circuit for a digital phase-locked loop." This Integrated Circuit (IC) features a digital phase-locked loop (DPLL) circuit along with DPLL Diagnostics circuitry. The DPLL circuit includes an oscillator and a digital phase detector, which generates a feedback signal indicative of the phase difference between the output signal and a reference input signal. This innovation enhances the monitoring and control of oscillators in digital systems.
