A highly integrated ultra-low-cost high-performance Bluetooth 3.0+EDR SoC is implemented in 0.11m digital CMOS technology. The transceiver has an integrated balun shared between TX and RX, eliminating the need for a separate T/R switch. A 4 LO-based VCO is implemented to reduce LO pulling and to minimize TX out-of-band spurious emissions. The transmitter(More)
For compact integration of 13.56MHz NFC functionality in mobile devices, a small planar loop antenna is a necessity. Active load modulation (ALM) is a commonly adopted technique to boost load modulation amplitude to overcome weak inductive coupling in small antennas. However, due to the challenges of phase synchronization, ALM is mainly limited to low data(More)
