Abstract :
The paper describes the ADC position-sense interface (PSI) for measuring response in proof mass on input acceleration. The explanation of the PSI function, describing advantages and disadvantages of this approach and the simulation results was the basic purpose of this work. The cancellation of the offset, parasitics and common-mode input voltage are depicted as well. The simulation results were taken by CADENCE design tool.
