A novel voltage reference has been proposed and simulated using a 0.18μm CMOS process in this paper. A near-zero temperature coefficient voltage is achieved in virtue of the bias voltage subcirciut which consists of two MOSFETs operating in the saturation region. The kind of bias voltage subcirciut is used to adjust the output voltage and compensate the curvature. The output voltage is equal to...

This paper presents the design and performance comparison of a two stage operational amplifier topology using CMOS and BiCMOS technology. This conventional op amp circuit was designed by using RF model of BSIM3V3 in 0.6 μm CMOS technology and 0.35 μm BiCMOS technology.

This paper describes an electromagnetic interference (EMI)resisting Bandgap voltage reference. Its basic topology is a Kuijk Bandgap with a PMOS pass device and an active load, improved to generate a low voltage output (441.3mV) via substituting BJT by MOSFET while preserving a low temperature coefficient (TC). A double differential pair and a power-supply independent bias jointly enhance the E...

In this paper a high efficiency PWM CMOS audio power amplifier is proposed. The original idea is based on the difference close-loop feedback technique and the difference pre-amp. Thus, we conceive a rail to rail comparator with a constant gm. This rail-to-rail PWM comparator with hysteresis architecture has been embedded in the audio power amplifier. The simulation results based on the TSMC 0.1...

The paper presents a bandgap voltage reference (BGR) implemented in TSMC 0.25 m BCD technology for an automotive application. To withstand a car's battery large voltage variations, from 5V to 40V, the circuit features an embedded pseudo-regulator providing a stable bias current for the bandgap core. High-voltage (HV) MOS count has been kept low thus allowing the design of a compact BGR with an ...
