Wireless communication system and method using digital calibration to control mixer input swing |
摘要 |
A wireless communication device is disclosed wherein the voltage swing of a local oscillator (LO) signal is controlled to prevent overstressing semiconductor devices in a mixer to which the LO signal is supplied. A quadrature divider supplies the LO signal to the mixer. Digital calibration methodology controls the current that the quadrature divider draws from a power supply to set the voltage swing of the LO signal that the quadrature divider generates.
