An improved analytical I-V model accounting for the influence of short-channel effects on radiation-tolerant doughnut transistors is presented. The model is validated using TCAD simulation of the devices. The impact of this layout style on the driving capability of the devices is also analyzed confirming that it is seriously compromised in the case of large(More)

This paper presents a first order Σ∆ Analog to Digital Converter for current measurement in motor controls. The converter consists of a time continuous differential integrator at the input with external capacitors and a four bit pulsewidth modulator in the feedback branch. Highly symmetrically switching inverters are used to couple the differential feedback(More)
Three 12 bit, 40 MS/s pipelined analog-to-digital-converters (ADCs) are developed in 0.35μm CMOS process with 3.3V single power supply. The proposed ADCs architectures study the influence of the amplifier sharing technique in the power consumption and the main performances in the pipeline ADCs. Simulations results with extracted netlists are provided and(More)
This paper deals with the design of a second-order /spl Sigma//spl Delta/ modulator in 0.18-/spl mu/m CMOS technology. The A/D converter structure combines a 1-bit approach along with a relatively high oversampling ratio in order to obtain a reasonable dynamic range. A circuit prototype, including the modulator itself, a current reference, and the clock(More)
