Latest Patents
Wang's latest patents include a Radio Frequency (RF) to Digital Polar Data Converter and a Time-to-Digital Converter (TDC) based Time Domain Signal Processing Receiver. This innovative technology focuses on polar data conversion, which improves signal-to-noise ratio (SNR) tolerance due to its phase convergence near the origin in polar coordinates. The proposed RF-to-Digital Converter consists of a TDC for phase detection and an analog-to-digital converter (ADC) for amplitude conversion. Unlike conventional data converters, the ADC's sampling position is guided by the detected phase result from the TDC's output. This architecture reduces the number of bits required for the ADC, eliminating the need for oversampling. With precisely controlled tunable delay cells and a gain compensator, this hybrid data converter can directly convert Quadrature Amplitude Modulation (QAM) and Amplitude Phase Shift Keying (APSK) waveforms from the RF signal without down-conversion. Consequently, the proposed architecture achieves lower power consumption and improved performance compared to traditional I/Q receivers.
