چکیده انگلیسی
Measuring signals in ultra-fast electronic systems requires high-end digital oscilloscopes characterized by extremely large analog bandwidths, up to 100Â GHz, and digitization capabilities at least up to the corresponding Nyquist rate, i.e. 200Â GS/s or above. This performance can be achieved by means of architectures that implement suitable methodologies, based on synchronous time interleaving, digital bandwidth interleaving, or hybrid approaches merging and exploiting both of the previous concepts. Each of these architectures typically includes a number of innovations, concerning both methods and hardware solutions, which are either covered by patents or classified. The paper presents the architecture of an original high-speed digitizer that exploits frequency conversion and time interleaving techniques. Thanks to the use of 4 time-interleaved channels, each one consisting of a state-of-the-art sampler and an ADC, the proposed solution can increase fourfold the analog bandwidth with respect to the individual ADCs, achieving noise reduction with respect to traditional time interleaved architectures.
