“…So a false alarm occurs when the noise level crosses the value of the decision threshold S D for at least one of the noisy samples during the symbol duration time. So, the probability of a false alarm is given by: where P is the number of samples during the symbol duration time T S given by (9). A non-detection occurs when a pulse is sent and the magnitude of the noisy signal remains lower than the decision threshold during the symbol duration time.…”

“…Passive solutions based on external filters or integrated filters can be used [7] to shape the pulse but they dramatically impact the size and the cost. Solutions based on active devices [8] [9] suite better the integration issues but need high tuning capabilities to compensate Process Voltage and Temperature (PVT) variations. In this context, several solutions have been proposed to control the shape of the [12].…”

This work presents a high rate IR-UWB transceiver chipset implemented in a 130 nm CMOS technology for WBAN and biomedical applications in the 3.1GHz-4.9GHz band. The transmitter is based on a pulse synthesizer and an analytical upconverted Gaussian pulse is used to predict its settings. Its measured peak to peak output voltage is equal to 0.9Vpp on a 100 load for a central frequency of 4GHz, and a supply voltage of 1.2V, which gives an emitted energy per pulse of 0.64pJ. The receiver is a non-coherent architecture based on a LNA followed by a peak voltage detector. A BER of 10-3 is measured for a 3.1GHz-4.9GHz input peak-to-peak pulse amplitude of 1.1mV which corresponds to a sensitivity of-85.8dBm at 1Mbps and gives a communication range estimated to 1.9m.

“…Similarly to the all-digital solutions comprising digital ring oscillators (RO) as RF sources [18], [19], [21], an ad-hoc designed ULP RO is simply duty cycled as an analog oscillator. Phase noise requirements at the transmitter are typically relaxed for an IR-UWB non-coherent energy detection receiver [26], enabling the use of a simple ring oscillator for signal generation. Compared to pulse shaping based designs turn-on time is not needed, as the RO can start oscillation instantaneously, ideally with no delay.…”

This paper presents a very low-complexity all-digital IR-UWB transmitter that can generate pulses in the band 0-5 GHz, requiring a silicon area lower than a PAD for signal I/O. The transmitter, suited to non-standardized low data rate applications, is prototyped in a 130 nm RFCMOS technology and includes analog control signals for frequency and bandwidth tuning. Center frequency is linearly selected with voltage supply, 0.5 V for the range 0-960 MHz and 1.1 V supply for the higher 3.1-5 GHz range. The architecture is based on the same delay cell for both baseband and radio frequency signal generation and pulses fractional bandwidth remains constant when voltage supply and control voltages scale. At 420 MHz center frequency, the transmitter achieves 7 pJ/pulse, and for 4 GHz center frequency pulses, it achieves 32 pJ/pulse active energy consumption. The OOK/S-OOK transmitter occupies an area of 0.004 mm . For ASK modulation, the system includes a separate on-chip capacitor bank connected to the output of the transmitter for an overall size of 0.024 mm . For pulse rates below 100 kpps, the generated pulses meet the FCC indoor mask with an off-chip DC block capacitor. The paper also presents over-the-air measurements using a planar monopole antenna operating in the 1.5-3.7 GHz frequency range.

“…3.15, the Pbias and Nbias biasing voltages control the current during transitions. The frequency can be tuned across a wide range (up to 5 GHz has been demonstrated in a 90 nm CMOS process) [16], thereby providing flexibility to tune the bands. The transistors can be sized for the same rise and fall times as well as to reduce process variability.…”
