The analog electronics is a challenging subject for undergraduate students in electrical engineering, due to the complex combination of many previous subjects, such as linear circuit analysis, signal and system, linear control theory and some sort of mathematics. This paper presents the modeling, analysis and design of the operational amplifier, which is used as benchmark system for analog elec...

Spontaneous retinal waves are critical for the development of receptive fields in visual thalamus (LGN) and cortex (VC). Despite a detailed understanding of the circuit specializations in retina that generate waves, whether central circuit specializations also exist to control their propagation through visual pathways of the brain is unknown. Here we identify a developmentally transient, cortic...

SUMMARY A lower impedance terminal is necessary for an input terminal of current-mode circuits and an output terminal of voltage-mode circuits to reduce an error and distortion in analog signal processing. ...

A high-linearity and high-speed current-mode sampleand-hold circuit is designed and simulated using a 0.25μm CMOS technology. This circuit design is based on low voltage and it utilizes a fully differential circuit. Due to the use of only two switches the switch related noise has been reduced. Signal dependent -error is completely eliminated by a new zero voltage switching technique. The circui...

A high-speed random number generator (RNG) circuit based on magnetoresistive random-access memory (MRAM) using an error-correcting code (ECC) post processing circuit is presented. ECC post processing increases the quality of randomness by increasing the entropy of random number. We experimentally show that a small error-correcting capability circuit is sufficient for this post processing. It is...

ABSTRACT Recent applications of pulse-coupled neural networks have demonstrated the need for a simple pulse-coupled neuron circuit which can easily be implemented in CMOS technology. The proposed cell uses a positive feedback circuit with two capacitors. One capacitor corresponds to the external sodium ion potential, and the other to the internal potassium ion potentid. This cell body circuit i...

A novel low power and Positive Feedback Adiabatic Logic (PFAL) combinational low power circuit is presented in this paper. The power consumption and general characteristics of the PFAL combinationallow power circuit arethen compared against two combinational low power circuit Efficient Charge Recovery Logic (ECRL), Conventional CMOS. The proposed PFAL combinational low power circuit design was ...

It is easy to write a circuit speciication in a pure functional language so that execution of the speciication simulates the circuit. It's harder to make an executable speciication generate the circuit's netlist without using impure language features. The diiculty is that a circuit speciication evaluates to a graph isomorphic to the circuit, so the speciication of a circuit with feedback will e...

Abstract This paper introduces a new parasitic-insensitive charge transfer circuit using active output voltage feedback. The proposed parasitic-insensitive charge transfer circuit uses a passive charge transfer circuit for maximum output voltage dynamic range. A feedback loop between the transfer and output nodes is formed using a unity-gain opamp to make the two nodes’ potentials same, which p...
