Patent ID: 8489044

Claim:
A wireless communication element, comprising: a transmit path configured to convert a digital signal output by digital circuitry into a wireless communication signal; a control path communicatively coupled to the transmit path and configured to monitor and control one or more operational parameters associated with the transmit path, the control path comprising: a coherent receiver configured to receive the wireless communication signal; and a bias circuit electrically coupled to the coherent receiver and configured to generate a bias current for the coherent receiver, wherein the bias current is equal to: a bandgap voltage supplied to the bias circuit divided by a resistance selected to approximately match a process resistance integral to the coherent receiver; minus a temperature-dependent current multiplied by a predetermined scaling factors; the bias current configured to bias a feedback digital-to-analog converter of the coherent receiver, such that the feedback digital-to-analog converter outputs a current proportional to the bias current.
