PROJECT DELIVERABLES
Report on metrological methods for characterisation of resistors and capacitors for their stability, tracking and non-linear behaviour down to and below -120 dB THD and of electronic switches for their injection currents and transients’ stability, as well as results obtained on a selected set of high-grade resistors and capacitors.
Report on the assessment of at least 2 designs for novel amplifiers (composite operational amplifiers (COPAs)) for integrator and front-end digital circuitry with zero drift, extremely high gain, low noise and error below 1 ppm. This includes the development of the metrological tools to evaluate their performance and the results from this evaluation.
Report on the development of a precision (< 50 ps jitter) timing solution for the ADC architectures with a galvanically isolated external trigger, lock-in and internal clock frequency output. This includes the development of the metrological tools to evaluate its performance and a comprehensive report on the jitter and synchronisation performance achieved.
