This paper, presents a novel low power current mode 9 bit pipelined a/d converter. The a/d converter structure is composed of three 2.5 bit stages and one 3 bit stage operating in current mode and a final comparator which converts the analog current signal into a digital voltage signal. All the building blocks of the converter were designed in CMOS AMS 0.35 μm technology, simulated, and then a prototype converter was manufactured and measured to verify the proposed concept. The performances of the converter are compared to performances of known voltage-mode switched-capacitance and current-mod

Abstract A low-power 16 bit 250KSa/s successive approximation analog-to-digital converter (SAR ADC) is designed. The capacitor array consists of a 2-segment sub-capacitor array and high sampling makes the coupling capacitance a unit capacitance, solving the problem of fractional capacitance mismatch. The power consumption is reduced by introducing a common-mode voltage during the switching process of the capacitor array. The circuit uses a 4-stage pre-amplifier and adds a dynamically latched comparator using output misalignment calibration to ensure high accuracy resolution. Simulated in DB Hi

In this work, an idea of a wideband, precision, power electronics programmable voltage source (PVS) is presented. One of the basic elements of the converter, the control section, contains a continuous-time sigma-delta modulator (SDM) with a pair of interconnected complementary comparators, which represents a new approach. In this case, the SDM uses comparators with a dynamic hysteresis loop (DHC) that includes an AC circuit rather than an R-R network.

Frequency reference oscillator is a critical component of modern radio transceivers. Currently, most reference oscillators are based on low-frequency quartz crystals that are inherently bulky and incompatible with standard micro-fabrication processes. Moreover, their frequency limitation (<200MHz) requires large up-conversion ratio in multigigahertz frequency synthesizers, which in turn, degrades the phase-noise.
