quantum-dot cellular automata (qca) is an emerging and promising technology that provides significant improvements over cmos. recently qca has been advocated as an applicant for implementing reversible circuits. however qca, like other nanotechnologies, suffers from a high fault rate. the main purpose of this paper is to develop a fault tolerant model of qca circuits by redundancy in hardware a...

SUMMARY In this paper, we propose an analog CMOS circuit which achieves spiking neural networks with spike-timing dependent synaptic plasticity (STDP). In particular, we propose a STDP circuit with symmetric function for the first time, and also we demonstrate associative memory operation in a Hopfield-type feedback network with STDP learning. In our spiking neuron model, analog information exp...

A 3-transistor non-volatile analog storage cell with 14 bits effective resolution and railto-rail buffered voltage output is presented. The memory, which consists of charge stored on a MOS transistor floating gate, is written by means of hotelectron injection and erased by means of gate oxide tunneling. The circuit allows simultaneous memory reading and writing; by writing the memory under feed...

This paper presents a design of an UWB downconversion integrated CMOS resistive ring mixer with Linear Voltage Regulator (LVR), to supply required biasing voltages for the mixer section. The designed mixer circuit has been optimized for using in heart rate extraction system with microwave Doppler radar at 2.4GHz frequency. This mixer needs 2 DC bias voltages equal to 0.5 and 1 volts for its bes...

The recent discovery of the memristor has renewed the interest for fast arithmetic operations via high-radix numeric systems. In this direction, a conceptual solution for high-radix memristive arithmetic logic units (ALUs) was recently published. The latter combines CMOS circuitry for data processing and a reconfigurable “segmented” crossbar memory block. In this paper we build upon such a conc...

Recently, there has been great progress in the fabrication of various nano-devices utilizing silicon ULSI processing techniques [1]. Reliable room temperature operations have been demonstrated in a silicon single-electron quantum-dot transistor [2], a silicon selfassembled quantum-dot transistor [3], and various types of single-electron memory cells [4,5]. However, these single electron or quan...

Spin Transfer Torque Random Access Memory (STT-RAM) has garnered interest due to its various characteristics such as non-volatility, low leakage power, high density. Its magnetic properties have a vital role in STT switching operations through thermal effectiveness. A key challenge for STT-RAM industrial adaptation is the write energy and latency. In this paper, we overcome by exploiting stocha...

Multi-threshold voltage CMOS (MTCMOS) is an effective technique for suppressing the leakage currents in idle circuits. When the conventional MTCMOS technique is directly applied to a sequential circuit however the stored data is lost during the low-leakage sleep mode. Significant energy and timing penalties are suffered to restore the pre-sleep system state at the end of the sleep mode with the...
