The multivibrator is a common circuit that consists of an amplifier with both positive and negative feedback (Figure 1a). When the output is positive, the positive input terminal equals ½V+, and the ...
Abstract: In this paper, we propose a novel active reconfigurable intelligent surface (RIS)-assisted amplitude-domain reflection modulation (ADRM) transmission scheme, termed as ARIS-ADRM. This ...
Abstract: This article proposes an amplitude–phase independent modulation mechanism and a transmitarray element based on this mechanism. The proposed mechanism can provide full range, linear amplitude ...
