Device and Method for Transferring Data Between a Transmitter and at Least One Receiver

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a device and method for extremely low-power data transmission between a transmitter and at least one receiver. It works by modulating the electrical capacitance of a transmission line using a voltage-controlled component, such as a diode or varactor, connected between the line and a reference potential. The transmitter sends data by altering the capacitance via a changing voltage signal, and the receiver detects and interprets these changes to extract the transmitted data. The method is specifically designed to minimize power consumption and thermal impact on the transmitter side.

Use CasesContent extracted from patent full text and abstract with AI.

• Transmitting data from quantum computers or other ultra-low-temperature computing systems, where even minimal heat generation can disrupt operations.
• Communication in battery-powered or energy-harvesting sensor networks deployed in remote or difficult-to-access locations.
• Data transfer in medical implants or wearable electronics, where minimizing energy use is critical for prolonged operation.
• Low-power communication in space systems or satellites, where energy is scarce and thermal management is crucial.
• Industrial automation systems with strict constraints on power consumption and electromagnetic interference.

BenefitsContent extracted from patent full text and abstract with AI.

• Extremely low energy consumption on the transmitter side, enabling data transfer without significant heat generation.
• Facilitates reliable data communication in environments sensitive to temperature increase, such as quantum computing cooled near absolute zero.
• Supports high data transfer rates (potentially over 500 Mbps) with low power.
• Uses standard semiconductor components (e.g., varactors or CMOS-transistors), making the approach practical and cost-effective.
• Can be integrated into both point-to-point and daisy-chained network topologies.
• Allows for robust data transfer even when the receiver operates at a much higher temperature than the transmitter.

Patent Abstract

In the device and the method for transferring data between a transmitter and at least one receiver, which are in communication connection by means of a transfer line, an electrical and/or electronic component having a capacitance which can be changed by means of a voltage signal is arranged between the transfer line and a reference potential (20). The transmitter (12) generates a voltage signal (US) which is changed over time and which represents data to be transferred. The voltage signal (US) changed over time is applied to the electrical and/or electronic component (18) in order to change its electrical capacitance and thus to change the electrical capacitance of the transfer line (16). In the at least one receiver (14), the electrical capacitance of the transfer line (16) and/or the change in the electrical capacitance of the transfer line (16) is measured, the changing electrical capacitance representing the transferred data.
