The novel CNFET-FCOA is further used to develop analog signal processing circuits such as noninverting amplifier, inverting amplifier, summer, subtractor
, differentiator, integrator, half-wave rectifier, full-wave rectifier, clipper, clamper, comparator, peak detector, and zero crossing detector.
(i) designing an architecture for adder and subtractor
by the minimal figure of cells, utilization area, and overall depleted energy,
Architecture is optimized for adder subtractors
and other resources hence demonstrating very low gate count of only 22k.
The function MSD_Sub_MB is constructed to simulate M+B subtractor
. In terms of the subtraction involving a conventional binary digit and an MSD digit, this function will firstly use bit-reversed method and then call MSD_Add_MB.
Lin, "A precise current subtractor
design", in Proc.
The circuit of the control function u consists of subtractor
circuit, sign function circuit, average absolute value detector circuit, and root circuit.
To realize the three reversible fused elements, the proposed design requires a reversible single precision floating point adder, a reversible single precision floating point subtractor
and a reversible single precision floating point multiplier.
In order to obtain cosine data from the new pipeline process, we put forward unidirectional rotation method to reduce the comparator and choose addition or subtractor
. [[theta].sub.m+1] should be expressed firstly.
The FTIR spectroscopy was performed using background subtractor
scan range of 400-4500 with wavelength range of 300-900 nm.
This [V.sub.dc] is subtracted from [V.sub.dcref] using an op-amp subtractor
Resource allocation involves allocating functional units like adder, subtractor
, multiplier and so forth and communication resources like buses and multiplexers and storage resources like registers and on-chip memory.
Model 1 is the filter without retiming and with adder, subtractor
, multiplier, and delay elements.
