Abstract
A new demodulator with consistent sensibility to signals received from different directions and low power consumption is provided. The demodulator may include a first demodulator branch and a second demodulator branch electrically connected in parallel, and a DC circuit to provide DC power to the demodulator. The DC circuit has a first diode and a second diode electrically connected in series between a DC power supply Vcc and the ground. The second demodulator branch can multiplex or reuse a bias current from the first demodulator branch.
