  • MIT Researchers Launch 5G Receiver 30x Better Than Traditional Models

    MIT Researchers Launch 5G Receiver 30x Better Than Traditional Models

    Key Takeaways

    1. 5G devices are causing increased signal interference for small, battery-operated gadgets like health trackers and environmental sensors.
    2. MIT has developed a passive filtering receiver that efficiently blocks unwanted signals using pre-charged capacitors and tiny switches.
    3. The new receiver operates on less than a milliwatt of power and occupies an area smaller than 0.05 square millimeters.
    4. It can block 30 times more harmonic interference compared to standard receivers, enhancing communication reliability.
    5. Future research aims to power IoT devices through ambient Wi-Fi or Bluetooth signals, potentially eliminating the need for batteries.

    As 5G devices become more prevalent, the airwaves are getting busier with signals. For small, battery-operated gadgets such as health trackers or environmental sensors, this noisy background can lead to interference that hampers communication. These compact devices can’t utilize the large, energy-consuming signal filters found in bigger electronics like smartphones.

    Innovative Solution

    The team at MIT has tackled this challenge by creating a receiver featuring a groundbreaking passive filtering method. This system incorporates a distinctive arrangement of pre-charged, stacked capacitors along with minuscule switches to prevent unwanted signals from being amplified. This innovative approach is highly efficient, allowing the whole receiver to use less than a milliwatt of power while maintaining an active area of less than 0.05 square millimeters. Remarkably, the new receiver is capable of blocking 30 times more harmonic interference compared to ordinary receivers.

    Engineering Excellence

    This level of efficiency is the result of smart engineering — employing the bootstrap clocking method to consistently power the switches, and taking advantage of the Miller effect, which enables small capacitors to function like much larger ones.

    The following Internet of Things (IoT) applications could gain the most from this advancement:

    Future Possibilities

    Researchers are currently investigating methods to power the chip by capturing ambient Wi-Fi or Bluetooth signals — a breakthrough that might eventually result in IoT devices that do not require batteries.
