Latest Patents

Liao's latest patents focus on enhancing digital modulation techniques. One notable invention is titled "Wideband Direct Modulation with Two-Point Injection in Digital Phase Locked Loops." This invention describes a digitally controlled oscillator (DCO) modulation apparatus that provides a wideband phase-modulated signal output. The exemplary modulator circuit employs an oscillator in a phase-locked loop that processes a wrapped-phase input signal. The invention involves unwrapping this signal to generate an unwrapped-phase signal, followed by differentiating the unwrapped-phase signal. By injecting both the wrapped-phase input and the differentiated signal into a feedback loop, Liao's circuit effectively addresses abrupt phase jumps that occur during the conversion process by using a multi-modulus frequency divider.
