A differential structure which has the ability to reject external vibrational noise for Metglas/Pb(Zr,Ti)O3 (PZT) fiber-based magnetoelectric (ME) heterostructures has been studied. This type of ME structure functions better than conventional sensors

International audience; By using nonlinearity effects in magnetostrictive - piezoelectric laminated sensors, modulation techniques can transfer low-frequency signals to higher frequencies. Theory predicts that the transfer ability depends mainly on t

A power-efficient low-voltage buffer is presented. The proposed buffer contains a low-frequency zero generation circuit to perform frequency compensation and a slew-rate enhancement (SRE) circuit to provide large dynamic current for driving the pass

This paper presents a low-voltage, low-quiescent current, low-dropout voltage regulator (LDO) with a novel capacitor-multiplier frequency compensation technique. The proposed compensation strategy can make the LDO stable under the entire load-current

1.0-V, 50-mA capacitor-less low-dropout (LDO) voltage regulator with 100pF internal output capacitor for SoC applications is presented. The proposed LDO makes use of a bi-directional asymmetric buffer (BDAB), which provides a signal inversion feedbac

A new frequency compensation scheme for multistage amplifier, named capacitor-multiplier frequency compensation (CMFC), is introduced. Increasing the capacitance with a current-mode multiplier in CMFC amplifier allows the circuit to occupy less silic

High-stability, high-accuracy low-dropout (LDO) voltage regulators are presented. The proposed LDOs make use of the slow-rolloff frequency compensation scheme which can enhance the stability, increase the loop gain and unit-gain frequency (UGF). This

A novel scheme is presented for achieving high performance low-dropout (LDO) voltage regulators under the constraint of low supply voltage. This scheme makes use of a frequency-dependent feedback factor (FDFF). The FDFF has simple circuit structure a
