ABSTRACT:
In an RF communication system, aspects of a method for a temperature sensor for transmitter output power compensation may comprise generating an output voltage, which may vary with temperature, from at least one reference voltage, wherein at least one reference voltage may vary proportionally with temperature. The output voltage may be converted to a digital value. The reference voltage may be generated by utilizing a current source to generate a voltage across a resistive load. A control voltage generated from an operational amplifier may control at least one current source. PN junction characteristics of at least one bipolar junction transistor may be utilized to generate an input reference voltage for the operational amplifier. Resistance of at least one resistor, which may be coupled to the bipolar junction transistor and to the operational amplifier, may be adjusted to determine a current level from the current source at a plurality of different temperatures.
