Abstract
This paper presents a fully-integrated 3–5 GHz-band
FM-UWB transmitter implemented in 90 nm bulk CMOS. The
front-end consists of an RF current-controlled oscillator (RF-ICO)
and class-AB power amplifier. Transmit data modulates a sub-car-
rier oscillator. The 2-FSK modulated output is ampli fied by a
transconductor, and directly modulates the RF-ICO tune input. A
successive approximation register (SAR) algorithm and on-chip
all-digital frequency-locked loop (FLL) calibrate the carrier
and sub-carr
