A low-power FSK/OOK transmitter for 915 MHz ISM band
A PLL-based, low-power, 915 MHz FSK/OOK transmitter is presented. The PLL uses gain-boosted LC VCO and hybrid injection-locked divider topologies to reduce power consumption with acceptable phase noise. In FSK mode, the transmitter consumes 367 μW from a 1.2 V supply with -18.6 dBm output power and achieves maximum 3 Mbps speed (122.3 pJ/bit). In OOK, power consumption is 314 μW with maximum 20 Mbps speed (15.7 pJ/bit). The transmitter occupies 0.29 mm2 of die area in a 130 nm CMOS process.
