| 520 | _ | _ | |a A SQUID system comprises a SQUID sensor and its associated readout electronics, which are essential for its operation. Despite its potential for high sensitivity to magnetic flux (or, field), the widespread use of SQUID systems has often been hindered by difficulties in producing and comprehending the required readout electronics. To overcome this challenge, recent research has taken a unique approach by considering the SQUID system from both the perspectives of the SQUID sensor and its accompanying readout electronics. There are two primary design concepts for SQUID systems: (1) employing strongly damped SQUID with very low intrinsic noise and minimizing the noise generated by the readout electronics to a value below the intrinsic noise of the SQUID sensor; or (2) creating a SQUID system where both noise sources, intrinsic SQUID noise and electronics noise, coexist and are approximately equal. However, implementing traditional design concept (1) for SQUID system presents significant challenges for the readout technique, whereas design concept (2) is comparatively easier to realize. In this comprehensive analysis, we summarize the SQUID readout principles of design concept (1), including conventional SQUID systems with flux modulation scheme (FMS), and further developments of this concept, such as additional positive feedback (APF), bias current feedback (BCF), noise cancellation (NC) and so forth. Furthermore, we introduce design concept (2), commonly referred to as the "weakly damped scheme." We explain and categorize all these readout techniques and discuss their advantages and drawbacks, aiming to provide a useful comprehensive analysis (an in-depth examination of SQUID readout) that bridges the gap between SQUID concept and its practical implementation. |
