摘要： Power detectors with temperature compensation and having improved accuracy over temperature are disclosed. Variations of a power detector gain over temperature is reduced by varying both the gate and drain voltages of MOS transistors within a power detector. In an exemplary design, an apparatus includes at least one MOS transistor (320), which receives an input signal (Vin), detects the power of the input signal (Vin) based on a power detection gain, and provides an output signal (lout) indicative of the power of the input signal (Vin). The at least one MOS transistor (320) is applied a variable gate bias voltage and a variable drain bias voltage in order to reduce variations of the power detection gain over temperature. At least one additional MOS transistor (322) may receive a second variable gate bias voltage and provide the variable drain bias voltage for the at least one MOS transistor.

The second gain path is configured to provide a second high frequency gain to the first signal. The second signal is generated by the transadmittance amplifier stage based on the gain recovery of the first signal and the high frequency gains of the first signal.

摘要： A switch-mode RFPA driver includes first and second field-effect transistors (FETs) arranged in a totem-pole-like configuration. The switch-mode RFPA driver operates to generate a switch-mode RFPA drive signal having a generally square-wave-like waveform from an input RF signal having a generally sinusoidal-like waveform. According to one embodiment of the invention, to maximize high-frequency operation and avoid distorting the switch-mode RFPA drive signal, the switch-mode RFPA driver is designed so that its output can be connected directly to the input of the switch-mode RFPA to be driven, i.e., without using or requiring the use of an AC coupling capacitor. The first and second FETs of the switch-mode RFPA driver are designed and configured to limit and control the upper and lower magnitude levels of the switch-mode RFPA drive signal to levels suitable for switching the switch-mode RFPA directly, obviating any need for DC biasing at the input of the switch-mode RFPA.
