Abstract
A one‐pin crystal oscillator (XO) employing a one‐pin startup and self‐charged architecture is proposed to reduce power consumption. The self‐charged circuit, replacing a constant‐current opamp, recharges crystal to save significant power. The proposed 32.768 kHz one‐pin XO, fabricated in a 0.18 μm CMOS technology, consumes 2.89 nW from a 0.25 V supply.
