Abstract

See full text

The disclosure discloses a lookup table-based circuit aging detection sensor, including a control circuit, two voltage controlled oscillators (VCOs), two shaping circuits, a phase comparator, a 3-digit voter, a beat-frequency oscillator, an 8-digit counter, a latch, a lookup table array and a digital-analogue converter. The control circuit respectively connects with the phase comparator, the 3-digit voter, the 8-digit counter, the first and the second VCOs. The first and second VCOs connect with the first and second shaping circuits respectively. The first and second shaping circuits connect with the phase comparator. The phase comparator connects with the 3-digit voter. The 3-digit voter connects with the beat-frequency oscillator. The beat-frequency oscillator respectively connects with the 8-digit counter and the latch. The 8-digit counter connects with the latch. The latch connects with the lookup table array. The lookup table array connects with the digital-analogue converter.
