We propose the use of Minimum Energy (ME) coding to improve the energy efficiency of an OOK transmitter. For the analysis, the power consumption model is based on a circuit which can completely switch off the transmitter during the transmission of 0 and which has an energy efficiency of 52 pJ/bit. It is shown that ME coding provides an improvement of energy efficiency to 30 pJ/bit for coding size k = 3. The improvement is more important when k increases, at the price of a reduced spectral efficiency and range decrease. Finally, the expression of an optimal coding size satisfying a given transmit range constraint is determined.
