Robust Design of CNFET Based Buffered Delay Model and Microwave Pulse Generator

Variation resilient reliable design of trigger pulse generator

“…Furthermore, on comparing the proposed design with low‐power designs such as [26, 27, 35, 36], it can be found that these designs are proposed to produce trigger pulses of a fixed duration for different low‐power applications. Similarly, the designs presented in [2, 4] require a very low supply voltage (0.7 V), the TPG can only produce trigger pulses of fixed duration which depends on the V DD . For instance, pulses of a fixed duration of 88.6 ps were obtained at a supply voltage of 0.7 V using design in [2].…”

“…For instance, pulses of a fixed duration of 88.6 ps were obtained at a supply voltage of 0.7 V using design in [2]. Additionally, CNFET based design suggested in [4] suffers from CNT‐specific imperfections. Thus, compared to [2, 4], that require 42Ts in the design, this work suggests incorporating an additional NMOS to control the current through the supply connecting the GND which is subsequently used to tune the duration of pulses as per the requirements.…”

Thus, the pulse width produced using the TPG circuit proposed in this work can be tuned to a wider range using an external control supply.…”

“…Hence, there is a dire need of high‐frequency pulse generators that can produce pulses of a precise duration, meanwhile consuming low power. Recently, TPG circuits using an XOR and delay elements have been suggested to mitigate some of the issues in the previously reported designs [2–4]. However, these trigger generators produce pulses of fixed duration and lack versatility in the application.…”
