The "Diploos" chip contains a large input inductor dc-SQUID with a 10 JJ array Q-killer inline with the input coil, a binary resistor array for additional positive feedback configuration (on right). This chip also contains a Resistive-SQUID (at
The Parametreo chip contains a Resistive-SQUID (on right) with pick-up coil inductively matched to a dc-SQUID input signal coil (center). A Binary resistor array for additional positive feedback configuration (far left). The Resistive-SQUID signal is amplified on chip by flux-locked dc-SQUID. All resistive elements are fabricated from trilayer of Ti/Pd/Au for milliKelvin operation.
