Inverter based comparators are proposed in the literature for medium speed ADCs with low power and low area requirements. The comparator is succeeded by a buffer in order to boost the gain of the comparator. This requires an additional delayed clock which limits the speed of the ADC. To overcome this limitation, a modified inverter based comparator which uses a single clock signal is proposed in this...
Multi Threshold CMOS (MTCMOS) circuit can be used to overcome the trade-off between speed and standby leakage current inherent in single threshold CMOS circuit. The simplest form is the dual threshold CMOS (DTCMOS), in which two threshold voltages are used in the same logic circuit. As a result, the standby power can be greatly reduced by this approach which is a key factor for battery operated devices...
Radiation Hardened By Design (RHBD) combinational circuits/primitive gates using 0.18um CMOS Technology is developed for Space application with help of Cogenda TCAD software suite. The proposed combinational cells are investigated for radiation simulation using three dimensional (3D) device structure. Single Event Transient (SET) caused by proton, α particle and heavy ions like C, Ar and Kr is observed...
Physical Unclonable Functions (PUFs) are promising security primitives in recent times. A PUF is a die-specific random function or silicon biometric that is unique for every instance of the die. PUFs derive their randomness from the uncontrolled random variations in the IC manufacturing process which is used to generate cryptographic keys. Researchers have proposed different kinds of PUF in last decade,...
