A 3.1 – 6.65 GHz, 933µW impulse radio pulse generator with tuneable spectrum in 0.18µm CMOS

An Efficient Method of Power Spectral Density Estimation for On-Chip IR-UWB Transmitter Self-Calibration

“…For instance, channels 2 and 3 of this standard are centered on 3993.6 MHz and 4492. 8 MHz respectively, which in combination with the emission masks imply challenging power limits for each channel. For the two channels shown in Fig.…”

“…However, impulse radio (IR) circuits are disturbed by process-voltagetemperature (PVT) variations that cause performance degradations, impacting notably the emitted pulse PSD shape and amplitude [8]. Therefore, to comply with the spectral masks of the IEEE 802.…”
