“…These circuits require a larger area as well as consume a large amount of power available to the circuit. Some other methods include a non‐linear transmission line or a step recovery diode [8] to produce pulses. However, these generators produce a moderately high level of random jitter and fluctuation in the parameters of pulses due to process, voltage and temperature (PVT) variations.…”

“…As compared to these traditional methods, which are capable of incorporating delays in the range of ns, the proposed buffered delay circuit proves to be more efficient [21]. SRD trigger pulse generators are economical but typically require several volts of input drive level and have a considerably high level of random jitter which leads to undesirable variations under PVT fluctuations [22]. As mentioned in Section 1, trigger pulses can also be generated using RC circuit employing very small time constants.…”

This paper proposes a circuit capable of incorporating buffered delays in the order of picoseconds. To study our proposed circuit in the profound way, we have also explored our proposed circuit using emerging technologies such as FinFET and CNFET. Comparisons between these technologies have been made in terms of different parameters such as duration of incorporated delays (pulse width) and its variability with supply voltages. Further, this paper also proposes a trigger pulse generator by utilizing proposed buffered delay circuit as its basic element. Parametric results obtained for the proposed trigger pulse generator match different application specific requirements. These applications are also mentioned in this paper. The proposed trigger pulse generator requires very low supply voltage (700 mV) and also proves its effectiveness in terms of tunability of pulse width of the generated pulses. The modeling of the circuit has been done using Verilog and the simulation results are extensively verified using SPICE.

This paper presents a fully tunable baseband ultrawideband (UWB) pulse generator, realized with commercial offthe-shelf components (COTS). It is made of high speed logic gates and comparators, and it is compliant with current mode logic (CML) digital standard. The pulse emitted power and bandwidth are tunable with pulse-width and amplitude variation, which shows high flexibility. This advantage simplifies the design of the downstream shaping network, as so to be compliant with international regulations. A differential output with very low jitter, and high pulse repetition frequency (PRF) is demonstrated.
