AB - A high-performance temperature-compensated crystal oscillator (TCXO) is presented. This paper proposes a new temperature sensor with a Σ–Δ analog to digital converter, and a voltage-controlled crystal oscillator, respectively, using two sets of independent power supply. The presented TCXO is implemented in a 0.35 μm 2P3 M standard complementary metal-oxide semiconductor process at a power supply of 3.3 V, and the total power dissipation is 21 mW. Measurement results indicate that the designed TCXO achieves ± 16 ppm output frequency tuning range and 135, − 141 dBc/Hz phase noise at 1, 10 kHz frequency offset, respectively, by using a 40 MHz fundamental AT-cut crystal resonator. With the temperature compensation, the frequency deviation is within ± 0.28 ppm over − 40 °C to 85 °C.
