This paper presents a miniaturized Bluetooth Low-Energy transceiver for IoT applications in 65-nm CMOS. A T/R switch embedded with transmitter harmonic suppression and on-chip impedance matching is proposed. A -94dBm receiver sensitivity is achieved with 2.3mW receiver power consumption. –56dBc of 2nd-order harmonic distortion and –48dBc of 3rd-order harmonic distortion suppressions are achieved with an 18.5% TX maximum efficiency. This transceiver satisfies the BLE radio specification without the need for external filters, that enables minimum size modules and a short time to market.
