Reversible, or information-lossless, circuits have applications in digital signal processing, communication, computer graphics and cryptography. They are also a fundamental requirement for quantum computation. We investigate the synthesis of reversible circuits that employ a minimum number of gates and contain no redundant input-output line-pairs (temporary storage channels). We propose new con...

By analyzing the working characteristics of binary Schmitt circuits we find their sequential characteristics, which makes us follow the method of sequential circuits to design Schmitt circuits. The sequential design technique is extended to the study of ternary Schmitt circuits in this paper. The designed ternary Schmitt trigger has a similar structure with a ternary flip-flop. PSPICE simulatio...

This work presents two current-mode integrated circuits designed for sensor signal preprocessing in embedded systems. The proposed circuits have been designed to provide good signal transfer and fulfill their function, while minimizing the load effects due to building complex conditioning architectures. The processing architecture based on the proposed building blocks can be reconfigured throug...

Different cascode circuits are investigated with regard to their suitability for low-voltage and low-current circuits. A generalized circuit representation is introduced and different cascode circuits are discussed with respect to their small-signal parameters as well as their associated dynamic output ranges. The output voltage ranges for saturation operation of the different cascode circuits ...

Negative feedback genetic circuits (NFGC) are key regulatory motif of cellular robustness with the capability of reducing noise in genetic interaction network. NFGC have the same control theory frame as negative feedback amplifier circuits (NFAC). NFAC can enhance gain stability and output signal-to-noise ratio (OSNR) of output signal (voltage). Whether NFGC possess these two advantages or not ...

Soft errors caused by particles strike in combinational parts of digital circuits are a major concern in the design of reliable circuits. Several techniques have been presented to protect combinational logic and reduce the overall circuit Soft Error Rate (SER). Such techniques, however, typically come at the cost of significant area and performance overheads. This paper presents a low area and ...

The inputs and clock signals combination sleep state dependent leakage current characteristics is analyzed and the optimal sleep state is examined in sub-65 nm dual Vt footed domino circuits. Simulations based on 65 and 45 nm BSIM4 models show that the conventional CHIL state (the clock signal is high and inputs are all low) is ineffective for lowering the leakage current and the conventional C...

Phase-locked loops (PLLs) are used in wireless receivers to implement a variety of functions, such as frequency synthesis, clock recovery, demodulation, and mixed-signal integrated circuits. Substrate coupling noise is a key problem in today’s large mixed-signal systems. Switching-noise generated by digital circuits can be coupled to sensitive analog circuits through the substrate, can degrade ...
