Low-Power Low-Complexity FM-UWB Transmitter in 130nm CMOS for WBAN Applications

In this paper, the design and implementation of a low power low complexity FM-UWB transmitter for WBAN applications is presented. The principle building stages of the proposed transmitter (subcarrier generator, RF oscillator, and power amplifier) are described. All circuits have been designed and implemented using Cadence Tool in 130nm CMOS technology. Our low-power FM-UWB transmitter covers the frequency band 3.4-3.9GHz and involves a class-AB power amplifier (PA) to deliver an output power $\gt -14$dBm to $a50 \Omega$ load antenna. The PA was also implemented in 130nm, 1.2V CMOS process along with other building blocks of the transmitter. The FM-UWB transmitter consumes $398 \mu W$ from 1.2V supply with 0.04mm
