Abstract [en]

Analog-to-digital converter (ADC) plays an important role in mixed signal processingsystems. It serves as an interface between analog and digital signal processingsystems. In the last two decades, circuits implemented in current-modetechnique have drawn lots of interest for sensory systems and integrated circuits.Current-mode circuits have a few vital advantages such as low voltage operation,high speed and wide dynamic ranges. These circuits have wide applications in lowvoltage, high speed-mixed signal processing systems. In this thesis work, a 9-bitpipelined ADC with switch-current (SI) technique is designed and implemented in65 nm CMOS technology. The main focus of the thesis work is to implement thepipelined ADC in SI technique and to optimize the pipelined ADC for low power.The ADC has a stage resolution of 3 bits. The proposed architectures combine adifferential sample-and-hold amplifier, current comparator, binary-to-thermometerdecoder, a differential current-steering digital-to-analog converter, delay logic anddigital error correction block. The circuits are implemented at transistor level in 65nm CMOS technology. The static and dynamic performance metrics of pipelinedADC are evaluated. The simulations are carried out by Cadence Virtuoso SpectreCircuit Simulator 5.10. Matlab is used to determine the performance metrics ofADC.
