Abstract(in English) | We present design improvement of integrated quantum voltage noise source (IQVNS) for high-performance Johnson noise thermometry systems. A main problem of our previous version of IQVNS was associated with lax synchronization with low- and high-frequency clock signals, which makes the whole system complicated and less robust. We have employed on-chip generation of low-frequency clocks by down-converting a high-frequency clock so that the whole circuit operates with a single clock. Counterflow clocking architecture has also been introduced both in chip and component block levels for achieving wider timing margins. The improved IQVNS has been fabricated by using our standard Nb-junction technology and successfully tested at low frequency. |
