Latest Patents
One of his latest patents is the "CMOS transceiver with dual current path VCO." This invention features a dual current path voltage controlled oscillator that ensures seamless frequency acquisition and uniform VCO gain reduction while maintaining original operating range and phase locked loop characteristics. The quad-channel transceiver includes a phase locked loop circuit with a voltage controlled oscillator for generating a clock signal, a FIFO buffer for data storage, and a frequency comparator for clock signal comparison. The folded starved inverter circuit within the voltage controlled oscillator provides two current paths, allowing for simultaneous coarse and fine phase tracking. This design achieves low jitter performance and a wide operating range, making it suitable for implementation in 0.18-μm CMOS technology, with a 10-bit error rate up to speeds of 3 Gbps.
Another notable patent is the "Tracked 3X oversampling receiver." This method involves generating a data sampling clock signal and comparing it to a received clock signal. The data sampling clock is utilized to sample a data signal into three distinct zones. The invention determines which zone has a transition in the data signal, indicating a direction of change for the data sampling clock signal.
