ASIC Implementation of low power variable resolution ADC

High resolution ADC dissipates high power and occupies large silicon area. A solution to save power in ADC is therefore to detect the current operating condition and vary the resolution accordingly.

In this ADC design, resolution is dynamically adjusted according to the given channel conditions. The approach followed in saving power is done by switching some of the stages of the ADC to the standby mode (depending upon the input strength) where power dissipation is only due to the leakage current.

The variable resolution ADC has been designed using Tanner tool on 500nm CMOS technology (AMIS_0.5_CFN kit) and chip is fabricated from MOSIS foundry.

This is the first chip fabrication done by my group in IIITA .

An Improved Dynamic Latch Based Comparator for 8-bit Asynchronous SAR ADC

Comparators are considered to be one of the rudimentary building blocks in most ADCs. Major criterion for an ADC design is high speed, low power and lesser real estate over the chip. In the conventional dynamic latched comparators a small input-voltage difference at the input terminals is pulled up to a full scale digital level in a short span of time, by a positive feedback mechanism (regenerative latch). Due to the random offset errors and internal parasitic/external load capacitances mismatches they suffer a lot of accuracy issues. To overcome this inaccuracy issue, the conventional architecture used a separate preamplifier stage anteceding the positive feedback stage due to which it could amplify a small difference in the input voltage to a full scale digital output, negating the kickback noise. But for an ADC with a feature of high speed and low power application, a comparator without the preamplifier is preferred since it suffers from high static power dissipation. The present work deals with increasing the speed of conversion for an 8-bit ASAR ADC which is done by incubating a modified dynamic latch based comparator as proposed. In the reset phase the output nodes has to be charged up to the initial supply voltage level. This charging of the output nodes induces latency in the process of comparison. We propose a modified approach to tackle this dead time required to reset and improve the speed of comparison. This will in turn make the ASAR ADC to fasten the process of conversion.
