Super-Regenerative RX

Technical Explanation

Traditional superheterodyne and direct-conversion receivers require multiple local oscillators, mixers, and multi-stage filters that consume milliwatts of power. Super-regenerative receivers employ an oscillating circuit that is periodically quenched, providing massive RF gain (>80 dB) in a single active stage. In 6G Ambient IoT tags, this enables nano-watt power decoding of base station interrogation beacons directly from harvested energy.

Key Functions

• Single-stage RF amplification achieving massive gain with sub-microwatt power draw
• Decoding cellular interrogation beacons without power-hungry local oscillators
• Extremely compact silicon footprint enabling sub-cent Ambient IoT microchip manufacturing
• High sensitivity capturing faint signals at the edges of cellular cell coverage
• Direct integration into flexible printed paper and smart packaging circuits
