“…A wideband FM demodulator is implemented as a delay-line demodulator that is shown in Figure 4 [15], [34], [44][45][46]. It transforms the FM to a phase-modulated (PM) signal via a delay line, and then multiplies it with the original FM signal through a multiplier [47] to produce an amplitudemodulated (AM) output suitable for envelope detection.…”

This paper surveys the research on frequency modulated ultrawideband (FM-UWB) transceivers. FM-UWB system uses low modulation index digital FSK followed by high modulation index analog FM to generate a constant envelope UWB signal with a flat power spectral density and steep spectral roll-off. FM-UWB can be seen as an analog implementation of a spread spectrum system with spreading gain equal to the modulation index. FM-UWB system is suitable for low data rate and short-range applications. The advantages of FM-UWB system such as low power consumption, very low radiated power (−41.3 dBm/MHz), good coexistence with other existing wireless technologies, and robustness to interference and multipath making it suitable for Wireless Body Area Network (WBAN) in medical applications. General TermsUltra-wideband (UWB), UWB transceivers.

“…Achieving an accurate fixed delay or a good control of delay tunability is important for the delay-line demodulator. The existing demodulator design with the two-stage current-reuse technique using the group delay of the all-pass filter (APF) or the band-pass filter (BPF) group delay has to employ many inductors [29], which increases the chip area significantly and suffers from poor tunability over PVT variation.…”

This paper presents a frequency modulated ultra-wideband (FM-UWB) transceiver system with RF submodules gated by a data-driven control signal. With the control signal, intermittent operation of key building blocks such as a VCO in the transmitter and a wideband FM demodulator in the receiver is realized. To enable an effective dynamic power control, the transmitter generates higher subcarrier frequency and modulation index than conventional FM-UWB transmitters by utilizing an 8-modulo fractional-N PLL in which a triangular waveform is generated by a relaxation VCO. In the receiver, an envelope detector monitors the presence of incoming signal and enables the data-edge-triggered power control for a wideband FM demodulator and other blocks. A prototype 3.5-4.1 GHz FM-UWB transceiver for on-chip wireline testing is implemented in -m CMOS. Experimental results show that the proposed gated FM-UWB system successfully demodulates the FSK information, achieving nearly 53% power saving with the data-driven power control enabled.
