This paper brings in a new design, namely, voltage mode differentiator with an active element,
Carbon Nanotube Field Effect Transistors Voltage Difference Transconductance Amplifier
(CNVDTA). The circuit thus proposed needs one Carbon Nanotube Field Effect Transistors Voltage
Difference Transconductance Amplifier (CNVDTA) element and a single capacitor. While fabricating
IC’s in VLSI design, the proposed circuit proves more adaptable and applicable with the anticipated
results.
Methods:
The proposed CNVDTA based voltage mode differentiator in CNFET technology was
simulated at 32 nm at a voltage supply of ±0.9 V using the Cadence Virtuoso CAD tool.
Results:
It is also reported that the proposed circuit would function with ±0.9 V supply voltage and
would also take care of the bias current of the order of 150 µA. Further, on the part of the transconductance
(gm), it is electronically tunable with the help of bias current.
Conclusion:
The CNVDTA based differentiator has been found to be very useful in the triggering circuit
of CRO’s, wave shaping circuits, power control circuits etc. It is also found useful in detecting the
high-frequency components in the input signals.
