Abstract :
In this paper, a 2.4GHz BLE-compatible transmitter architecture for use in ultra-low-duty-cycle applications has been presented. Low-voltage operation, extensive power gating and a negative-gate-biasing technique help in achieving a peak TX efficiency of 43.7% at an output power of +10.9dBm while also reaching a leakage power of 370pW, for an on/off ratio of 7.6×107.
