A power detector having a differential input unit and a differential output unit. In one aspect, the invention may be a power detector including a differential input unit including a differential input terminal to which an AC signal is input and a DC voltage generator which generates and outputs a DC voltage; and a differential output unit including a differential output terminal which full wave rectifies the AC signal input from the differential input unit and outputs a differential signal, wherein a negative output terminal of the differential output terminal is connected to the output terminal of the DC voltage generator.

Power detector

Disclosed is a self-correlation receiver of a transceiver in which a transmitter shares an antenna with a receiver. The self-correlation receiver includes: a clamper which receives a received signal, limits the magnitude of the received signal within a predetermined range and outputs a clamping signal; and a mixer which receives the received signal and the clamping signal and outputs a signal having a difference frequency between the received signal and the clamping signal.

Self-correlation receiver and transceiver including the same

There is provided an apparatus for duty cycle correction. The apparatus for duty cycle correction comprises a moving sum unit performing a moving sum calculation with respect to the square-wave signal and outputting the moving sum signal subjected to moving sum calculation, a comparison unit comparing the moving sum signal with a predetermined threshold voltage, outputting a high signal or low signal, a mean value calculation unit calculating the mean value of an output signal outputted from the comparison unit, the output signal being included in a section having a period integer times greater than that of the square-wave signal, and a threshold voltage control unit comparing the mean value with a middle value, increasing the threshold voltage when the mean value is greater than the middle value, and decreasing the threshold voltage when the mean value is less than the middle value.
