Built-in Radio Calibration
• Built-in calibration ensures repeatability and consistency
– Controls the effects of process variation to achieve the
highest yield on a bulk CMOS process
– Minimizes the effects of temperature variations during
operation
• Calibrates all major blocks of the radio to within 2% of target
• Filter phase and gain characteristics
• Gain blocks and matching between major components
• Center Frequency
– Does not affect the normal operation and occurs in the
normal Tx to Rx switching time – within 10 Psec.
