Abstract

A 0.6 V full wave rectifier with current mode nested and periodic feedback loops is presented, for the improved dynamic range with the low supply voltage. Compared with the conventional rectifiers, the rectifier with the loops is characterized by the micro feedback loop nested in the periodic macro one, so as to enlarge the dynamic range of the current mode signal with the ultra power supply voltage. With the technique, the dynamic range of the fully rectified signal should be optimized. Fabricated with a 0.18 µm CMOS process, with the typical 0.6 V supply voltage, the minimum amplitude of the fully rectified signal reaches 10 nA with the input signal bandwidth of 10 kHz and the power dissipation of 50 nW.
