摘要：
An analog-to-digital converter (ADC) suitable for measuring on-die DC or low frequency analog voltages may include a ring oscillator having a group of circuit cells successively and circularly coupled. Under certain circumstances, the ring oscillator may produce an output frequency that corresponds substantially linear to the input voltage. Other embodiments may be disclosed or claimed.
