IMEC, Renesas Electronics Announce New Bluetooth Transceiver for IoT

14 February 2018

At the 2018 International Solid-State Circuits Conference (ISSCC 2018) Imec and Renesas Electronics announced the introduction of a new, low-voltage (0.8 V) and ultra-low-power Bluetooth® Low Energy (BLE) transceiver specially designed for IoT.

They claim that this chip will extend battery life by 50 percent. In addition, the chip will allow a less complex power management unit, and it is designed to operate using non-standard energy sources such as energy harvesters.

The device is implemented on a 40 nm CMOS chip and consists of a phase-tracking receiver, a digital transmitter based on an all-digital phase-lock loop (ADPLL) to ensure precise frequency control.

Some features of the chip include:

  • A -95 dBm sensitivity for the receiver.
  • Power consumption is only 2.3 mW for the receiver.
  • The transmitter core area is only 0.8 mm2, including on-chip matching
