Abstract: TRANSCEIVERS FOR WIRELESS SENSOR NETWORKS (WSNS) AND WIRELESS BODY AREA NETWORKS (WBAN) REQUIRE HIGH DATA RATES AND LOW POWER CONSUMPTION TO OPERATE FOR LONG PERIODS OF TIME ON A BATTERY WHILE SATISFYING THE THROUGHPUT REQUIREMENTS OF THE APPLICATION LAYER. THE FIRST WORK PRESENTS A FREQUENCY CALIBRATED TRANSMITTER OPERATING IN THE 433.92MHZ FREQUENCY BAND TO MAXIMIZE THE DATA RATE IN THE SMALL CHANNEL BANDWIDTH. THE OOK TRANSMITTER ACHIEVES A TUNING RANGE OF 54-MHZ AND A FREQUENCY RESOLUTION OF <140-KHZ OVER THE ISM BAND OF 433.05-MHZ TO 434.79-MHZ. A COARSE SUCCESSIVE-APPROXIMATION-REGISTER BASED AND FINE TIME-TO-DIGITAL-CONVERSION CALIBRATION ARCHITECTURE IS PROPOSED THAT COMPLETES CALIBRATION IN LESS THAN 18.5-US. WITH A SIMPLE SPEED-UP CIRCUIT FOR THE OSCILLATOR, THE TRANSMITTER ACHIEVES A DATA RATE OF 1-MBPS AT AN OUTPUT POWER OF -13.5-DBM. THE SECOND WORK PRESENTS A 2.4GHZ ENERGY EFFICIENT OOK TRANSMITTER AND SUPER-REGENERATIVE RECEIVER FOR HIGH DATA RATES. THE TRANSMITTE
