A superconducting analog track-and-hold circuit

A superconducting analog track-and-hold circuit has been designed, fabricated, and tested. Experimental results demonstrate a 1.2-GHz bandwidth and a 25-dB dynamic range. Model calculations indicate that an optimized circuit with a critical current density of 10000 A/cm/sup 2/ can achieve a 4-GHz ba...

Description
Summary:A superconducting analog track-and-hold circuit has been designed, fabricated, and tested. Experimental results demonstrate a 1.2-GHz bandwidth and a 25-dB dynamic range. Model calculations indicate that an optimized circuit with a critical current density of 10000 A/cm/sup 2/ can achieve a 4-GHz bandwidth and a 35-dB dynamic range.< >
