A method to compensate the influence in amplitude and phase of the Analog-to-Digital Converters (ADC) and transducers used in the CEM sampling wattmeter, has been evaluated. The influence of the ADC has been tested and an algorithm to compensate for amplitude and phase has been implemented. Similar algorithm has been also developed to compensate for the influence of the shunts and resistive dividers...
We propose and experimentally demonstrate the first THz-bandwidth on-chip fractional Hilbert transformer based on an integrated phase-shifted waveguide Bragg grating on silicon. Experimental results show an error of only 0.24 % at 940 GHz bandwidth.
