A digital CMOS buffer circuit with a voltage transfer characteristic (VTC) with low threshold voltage detection, hysteresis, and high noise immunity is presented. The circuit is capable of restoring slow transition times and distorted input signals with a minimum delay penalty, offering at the same time high noise immunity to glitches induced either through capacitive coupling or from the power...

this paper proposes a low voltage (±0.55v supply voltage) low power (44.65µw) high common mode rejection ratio (cmrr) differential amplifier (d.a.) with rail to rail input common mode range (icmr), constant transconductance (gm) and enhanced frequency performance. its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...

Three novel differential precision rectifier circuits are realized using single CMOS differential voltage current conveyor. One of the realized differential precision rectifiers provides half wave voltage output. The other two circuits give full wave voltage outputs. Among the two full wave differential precision rectifiers, one circuit provides single ended voltage output while other full wave...

The inverse problem of electrical impedance tomography (EIT) is to recover the conductivity inside an investigated object from boundary measurements of current and voltage. There is a variety of methods to localize inclusions, i.e. domains in which the conductivity is different from the background conductivity such as e.g. the Factorization method. However, these qualitative methods don’t provi...

A novel method for the reduction of subthreshold slope below the room-temperature Boltzmann limit of 60 mV/dec for a field-effect transistor based on negative differential capacitance is proposed. This effect uses electric field induced electrostriction of a piezoelectric gate barrier of the transistor. The mechanism amplifies the internal surface potential over the applied gate voltage. This i...
