Abstract
A millimeter-scale Bluetooth low energy wireless transmitter is presented with a dual purpose loop antenna. The oscillator employs a high quality factor resonator formed by a printed 3.5×3.5 mminductive loop antenna (simulated Q˜110) and an on-chip digitally-switched capacitor array (simulated Q˜283). The oscillator replaces the traditional voltage controlled oscillator plus power amplifier, achieving lower power consumption while maintaining phase noise of −118.5 dBc/Hz at 1 MHz offset that results in low FSK modulation error (2.1%) and low frequency drift during BLE packet transmission.
