Abstract

The ever-increasing sizes of transition-edge sensor (TES) microcalorimeter arrays motivates improved multiplexed readout with large multiplexing factors, low power dissipation, and low levels of crosstalk. Current-summed code division multiplexing (I-CDM) has been proposed as an alternative to flux-summed code division multiplexing (Φ-CDM) because of its lower power dissipation and greater robustness against the failure of individual readout elements. Simulating I-CDM arrays, we find that unswitched circuit components provide a mechanism for crosstalk, the magnitude of which is determined by their inductance. To mitigate this source of crosstalk, we propose a technique called resonator-stabilized I-CDM (RI-CDM), which the simulations predict will reduce crosstalk by an order of magnitude. RI-CDM reads out dc-biased TESs on an amplitude-modulated carrier wave.
