Latest Patents

One of Yi-Cheng Wu's latest patents involves a phase lock loop that includes a quantization circuit. This circuit generates an out-of-phase noise cancellation signal from an error in a delta-sigma modulator and applies the noise cancellation signal to the charge pump. The quantization circuit features a digital-to-analog differentiator, which may be a single-bit first-order or second-order differentiator, or a full M-bit binary-weighted digital-to-analog differentiator. Another significant patent is for a cross-coupled high-frequency buffer. This local oscillator (LO) buffer circuit comprises first and second LO buffers arranged in a cross-coupled configuration. The first LO buffer generates in-phase output signals in response to in-phase input signals, while the second LO buffer generates quadrature output signals from quadrature input signals. The LO buffers may include inductive loads and utilize MOS transistors or bipolar junction transistors.
