Abstract
Methods and systems for a wideband CMOS RMS power detection scheme may comprise: a first circuit including a first metal oxide semiconductor (MOS) transistor having a gate for receiving a radio frequency (RF) signal and having a drain for outputting a first current that is proportional to a square of a voltage of the RF signal in response to receiving the RF signal; and a second circuit connected to the first circuit, the second circuit comprising a second MOS transistor biased in a triode region and having a source for receiving the first current from the first circuit. The second circuit may output a voltage proportional to a power of the RF signal received by the first circuit, the output voltage being a function of the first current and a channel resistance of the second MOS transistor.
