A 12 bit 120 MS/s SHA-less pipeline ADC with capacitor mismatch error calibration

A 12 bit 76MS/s SAR ADC with a Capacitor Merged Technique in 0.18µm CMOS Technology

A new high-resolution and high-speed fully differential Successive Approximation Register (SAR) Analog to Digital Converter (ADC) based on Capacitor Merged Technique is presented in this paper. The main purposes of the proposed idea are to achieve high-resolution and high-speed SAR ADC simultaneously as well. It is noteworthy that, exerting the suggested method the total capacitance and the rat...

A Mismatch-Immune 12-bit SAR ADC With Completely Reconfigurable Capacitor DAC

We overcome mismatch constraints of capacitor DAC design in SAR ADCs using a completely reconfigurable DAC with content addressable memory beneath groupings of unit capacitors. We demonstrate a linearity optimization technique in simulation and measurement. We achieve a nearly 2-bit repeatable ENOB improvement with a peak of 11.3 bits.

A 12-bit high performance low cost pipeline ADC

This paper presents the design and implementation of a 2.5V 12-hit high performance and low cost pipeline Analog-to-Digital converter (ADC) architecture using CMOS technology. A modified flash ADC was employed instead of the traditional flash ADC to implement the sub-ADC in the designed pipeline ADC scheme to reduce the device complexity and attain lower system power consumption. The designed p...

Pipeline ADC using Switched Capacitor Sharing Technique with 2.5 V, 10-bit

This paper presents 10-bit, 1.5 MS/s, 2.5V, Low Power Pipeline analog to digital converter using capacitor coupling techniques. A capacitance coupling folded-cascade amplifier effectively saves the power consumption of gain stages of ADC in a 0.25 μm CMOS technology. The ADC also achieves Low power Consumption by the sharing an op-amp between two successive pipeline stage further reduction of p...
