Abstract

A 2.4 GHz on-off keying (OOK) transmitter with high data rate up to 136 Mb/s for biotelemetry applications has been designed in a 0.18 μm CMOS process. Power consumption of the transmitter is reduced by 38 percent with the proposed mechanism of switching an oscillator on and off to generate an OOK modulated signal. The TX for 136 Mb/s OOK data has a DC power consumption of 3 mW and an output power of -14 dBm. The TX achieves energy efficiency of 22 pJ/bit with an associated BER of 1.7×10^-3. The TX, including a 2.4 GHz omni directional antenna, is implemented on a printed-circuit board measuring 8×9 mm² in size.
