Apparatuses and methods for enabled switch detection are disclosed. In one embodiment, an apparatus includes a complimentary metal oxide semiconductor (CMOS) switch having a gate, a drain, a source, and a well. The source and drain are formed in the well, and the gate is formed adjacent the well between the source and drain. The source is configured to receive a radio frequency signal from a first power amplifier. The apparatus further includes a switch enable detect block configured to compare a signal indicative of the gate voltage of the first switch to a first reference signal and to generate an output comparison signal based at least partly on the comparison. The apparatus further includes a power amplifier bias control block configured to enable the first power amplifier based at least partly on the output comparison signal from the switch sense block.
