This paper presents a Resolution Adaptive Flash A/D Converter design and its performance. To achieve high speed, the proposed A/D converter utilizes Threshold Inverter Quantization technique replacing conventional analog comparators with digital comparators. The replacement results in a faster digital conversion and a reduction of the analog nodes in the ADC. The proposed ADC is a true variable resolution...
This paper introduces a novel current sense amplifier (CSA) in sub-32nm fully depleted (FD) double-gate (DG) silicon-on-insulator (SOI) technology with planar independent self-aligned gates. A new architecture is proposed which takes advantage of the back gate in order to improve circuit properties. Compared to the reference circuit, the new architecture proves to be faster (21% sensing delay decrease),...
In this paper, a 12-bit 50MHz Pipelined Low-Voltage ADC is presented, which consists of 8-stage-pipelined low resolution ADCs and a 4-bit flash ADC. Several critical technologies are used to guarantee the resolution and high sampling and converting rate such as 1.5bits per stage conversion, digital correction logic, gain-boosted telescopic OTA and so on. Finally the whole system is taped out in SMIC...
