Low Offset, High PSRR, CMOS Bandgap Voltage Reference
A CMOS Bandgap Voltage Reference (BVR) with the characteristics of low offset and high power-supply rejection ratio (PSRR) is presented. In order to reduce the effect of offset of operation amplifier (OPA), the voltage difference of base-emitter junctions of substrate bipolar transistors is maximized; meanwhile the factor of offset voltage could be minimized. The feedback loop constructed by pr...
متن کاملHigh PSRR, Low Power Bandgap
This paper describes a new Bandgap Reference (BGR) architecture with low power consumption and high Power Supply Rejection Ratio (PSRR). Implemented in a 65nm CMOS technology, the circuit includes a pre-regulator, a current source and also digital validation for the bandgap voltage. The current consumption is below 4.9μA at 50oC, PSRR of -110dB@1kHz and -61.3dB@10MHz. The reference output volta...
متن کاملA 104μW EMI-resisting bandgap voltage reference achieving -20dB PSRR, and 5% DC shift under a 4dBm EMI level
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...
متن کاملA Low-Voltage High PSRR and High Precision CMOS Bandgap Reference
By adopting the technique of pre-regulator, a high PSRR and low temperature coefficient piecewise-linear bandgap reference (BGR) is designed for analog and mixed-signal application in this paper. The piecewise-linear BGR with pre-regulator, which is analyzed and simulated in SMIC 0.18μm CMOS process, has simple circuit architecture. Simulation results show that piecewise-linear BGR with pre-reg...
متن کاملA Low-Impedance, Sub-Bandgap 0.6μm CMOS Reference with 0.84% Trimless 3-σ Accuracy and –30dB Worst-Case PSRR up to 50MHz
Modern mobile applications demand high performance from low supply voltages to reduce power (extend battery life) and survive low breakdown voltages (imposed by sub-micron CMOS technologies), which is why precise low-impedance subbandgap references (below 1.2V) that are independent of process, package stress, supply, load, and temperature are critical. However, improving dc accuracy by trimming...
