Conventional Superconducting Quantum Interference Devices (SQUIDs) have been used since the middle of the 60s to measure magnetic and electrical quantities. The critical point in using of the SQUIDs was a small value of the flux-to-voltage transfer coefficient. It required using of matching transformer and lock-in technique to receive a noiseless amplification. To increase the transform coefficient several new design of SQUIDs were offered in the last decade. In this report the new SQUIDs are described and a comparative analysis of their performance is given. Perspectives of wide-band devices based on the new SQUIDs and cooled semiconductors elements are discussed. New fields of application of the superconducting-semiconducting elements are considered.
