Carbon nanotube (CNT) is one of the embryonic technologies within recent inventions towards miniaturization of semiconductor devices and is gaining much attention due to very high throughput and very extensive series of applications in various analog/mixed signal applications of today’s high-speed era. The carbon nanotube field effect transistors (CNFETs) have been reconnoitred as the stimulating aspirant for the future generations of integrated circuit (IC) devices. CNFETs are being widely deliberated as probable replacement to silicon MOSFETs also. In this paper, different analog signal processing applications such as inverting amplifier, noninverting amplifier, summer, subtractor, differentiator, integrator, half-wave and full-wave rectifiers, clipper, clamper, inverting and noninverting comparators, peak detector, and zero crossing detector are implemented using low-power folded cascode operational amplifier (op-amp) implemented using CNFET. The proposed CNFET-based analog signal processing applications are instigated at 32 nm technology node. Simulation results show that the proposed applications are properly implemented using novel folded cascode operational amplifier (FCOA) implemented using CNFET.

“…With the exception of the ADC, all of the other HIGHTECS ASIC blocks have been custom designed during the project. The signal conditioning unit processing the high voltage frequency signal was integrated onto the HIGHTECS ASIC [6], [29], and requires only two pairs of external resistors and capacitors for signal conditioning and six external resistors for ESD protection. The block diagram of the frequency signal conditioning unit is presented in Fig.…”

“…During testing, a sawtooth wave with 70 V pp and 0 V offset was applied at the input of the frequency signal conditioning unit. The output data was read in from the ARINC data bus of HIGHTECS ASIC [6], [29]. The high voltage amplifier is based on the TI OP454 operational amplifier with supply voltage of up to ±50 V. It operates only at room temperature and is connected through a high temperature cable assembly to the evaluation board.…”

This paper covers the development and testing of a high temperature signal conditioning unit capable of sensing wide dynamic range signals from rotating sensors. The unit includes a current peak detector block, a digital pulse generator, ESD (electrostatic discharge) protection and generates an output current proportional to the peak value of the applied input signal. The digital data from the unit can be directly utilized by the FADEC (Full Authority Digital Electronic Control) system or the EHMS (Engine Health Monitoring System) on an aeroengine. The mixed signal unit presented in this paper was designed and fabricated on 1 μm silicon-on-insulator (SOI) CMOS (complementary metal oxide semiconductor) technology and has been shown to function up to 235 • Celsius with very high linearity of the output signal. This is the highest operating temperature of an integrated signal conditioning unit developed for a civil aircraft. The mixed signal unit was mounted on a high temperature hybrid module and helps reducing the weight of the aeroengine by several kilograms.Index Terms-Aeronautical rotating systems, CMOS SOI, high temperature electronics, peak detector.
