—A fully integrated 3.3 V-to-1.2 V supply voltage regulator for application in IEEE 1394B PHY has been designed in 0.13μm SMIC Mixed Signal process technology. The regulator is able to deliver peak current transient of 300 mA, while the output voltage remain within a margin of 10% around the nominal value. The PSRR response larger than 52 dB for frequencies up to 10 kHz under the condition of ...

This el The operational amplifiers are the primary blocks of most of the analog systems and mixed-signal integrated circuits. In most electronic devices, ripple noise in supply line is unavoidable. Hence a robust noise performance at high frequencies is required. This performance regarding the stability of OPAMP improves with help of frequency compensation techniques. The different compensation...

Abstract This paper presents a comparative EMI susceptibility study of different integrated operational transconductance amplifier (OTA) topologies. We analyzed conventional well-known topologies based on the Miller OTA and folded cascode concepts with lower power consumption. The output dc voltage shifts induced by supply input common mode high frequency disturbances are presented. On top comp...

In this paper, a band gap voltage reference using MOSFETs in strong inversion region is presented. The proposed circuit represents a high PSRR (Power Supply Rejection Ratio) and low temperature sensitivity and is capable of operating properly at supply voltages lower than 1v. In the designed circuit, the PSRR is improved using regulated voltage and a feedback loop. In addition, the circuit is i...

In the automotive domain, vast majority of testing is performed through simulations, which can validate a system design before actual implementation and emphasize eventual faults in process. Hence, simulation utmost importance. Behavioral models are necessary for creation each electronic device desired system, some components have very complex behavior: low-dropout linear voltage regulators (LD...

A new fully differential (FD) low input impedance CMOS current buffer with low voltage, and low power operation is presented. The low input impedance is achieved by remarkable reduction of the input node voltage swing using a novel double feedback scheme. Some advantages of the proposed double feedback scheme over the conventional (either positive or negative) feedback techniques are: lower inp...
