In this paper, a 10–bit 50–Msample\s pipelined ADC by using dynamic charge injection technique is presented. By the proposed scheme, the input voltage range is increased and powerconsumption is reduced. For the calibration of the output codes, a new method is presented which uses polynomial inverse function.By the use of the inverse function and simultaneously adjustment of both the weights of stages and coefficients of polynomials,linearity is achieved. The proposed ADC is designed and simulated in a 90–nm CMOS technology. Simulation results show that the ADC achieves a peak signal–to–noise–and–distortion ratio(SNDR) of 59 dB, a peak spurious–free dynamic range (SFDR) of 72.5 dB. The ADC’s power consumption (without calibrationcircuitry) is 1 mW (without calibration circuitry<\div>

An accurate bandgap voltage reference (BVR) which utilizes the thermal behavior of the threshold voltage and electron mobility of NMOS transistors is presented in thispaper. The circuit is based on a well–known addition of a proportional to absolute temperature (PTAT) and complementary to absolute temperature (CTAT) references. ThePTAT circuit uses the temperature coefficient (TC) of the electron mobility and the CTAT circuit uses the TC of thethreshold voltage to generate accurate PTAT and CTAT currents. The circuit is designed in a 0.18μm CMOS technology.Simulation results show a temperature coefficient (TC) of 3ppm and power supply rejection ratio (PSRR) of 77dB at DC frequency.<\div>
