Abstract
There is provided a receiver with a sigma-delta structure, the receiver including: a low noise amplifier amplifying a received signal according to a detection signal; a mixer converting an RF signal of the low noise amplifier into an IF signal; a sigma-delta A/D converter converting the IF signal from the mixerinto a digital signal; a 1 bit detector determining whether a voltage of the output signal of the mixer is greater than that of a predetermined reference voltage and outputting the detection signal including a result of the determination; and a demodulator obtaining an FFT result with respect to the signal from the sigma-delta A/D converter and adding or subtracting a predetermined gain value to or from the FFT result to calculate received signal strength indication (RSSI).
