Abstract

A fully-integrated 3-5GHz-band FM-UWB transmitter implemented in 90nm bulk CMOS is described. The transmitter includes: a sub-carrier oscillator, a voltage reference, a transconductance amplifier, a RF current-controlled oscillator and a power amplifier. Self-calibration circuitry based on all-digital frequency-locked loop (FLL) using a successive approximation register (SAR) algorithm is included on-chip. The 0.2 × 0.5mm² active area transmitter consumes 900μW from a IV supply. Energy consumption is 9nJ/bit at continuous data rate of 100kbit/s.
