A direct conversion receiver with DC offset compensation. The receiver includes an antenna receiving a RF signal, a mixture module converting the RF signal to a baseband signal, a gain amplifier amplifying the baseband signal, an adder subtracting a DC offset current from the baseband signal, a DC offset cancellation circuit obtaining and converting a DC offset value to the DC offset current, a track-and-hold circuit receiving the baseband signal, holding and transferring a DC offset voltage to the DC offset current, and a switching circuit alternatively coupling and decoupling the DC offset cancellation and track-and-hold circuit to receive the baseband signal.
