Abstract:

A 0.12 μW power dissipation quartz oscillator with 32,768 Hz frequency was designed and fabricated. Stability of the oscillator versus power supply and temperature variations was measured. The design is suitable for the role of the RTC (real-time clock) or main system clock in low-power, battery-powered and energy harvesting systems.
