In the 1970s, CMOS technology was finding its way into analog design through switched-capacitor circuits. The availability of simple switches and high impedance nodes in CMOS afforded more efficient sampling and holding of signals than in bipolar technologies. Most of the high-performance filters, sigma-delta modulators, and data converters are based on switched-capacitor (SC) techniques.
In this project, you will study the operation and design properties of op-amps, bias circuits, integrators and finally the 6-th order filter.

Some architectures will be analyzed during evaluation study and the results will be compared. The circuits will be designed under required performance constraints of minimal power, layout area, signal cross talks and noise reduction using advanced IC technologies. The students will be responsible for the circuit requirements, analysis and specifications definition, focusing on the readout noise performance. Circuit design and simulations and analog layout will be done using Cadence tools.
