| Abstract: | An analog TCXO(Temperature-Compensated Crystal Oscillator)chip was designed in a 0.35 μm CMOS process.A novel cubic functional variation of voltage circuit with embedded E2PROM Auto-trimming has achieved a temperature compensation function;To further enhance the output frequency stability,a stable oscillator circuit was designed to eliminate the impact of supply voltage.The test results showed that the ATCXO achieved ±2.0×10-6/-40 ℃~100 ℃,frequency stability with the supply voltage ±1.5×10-6.The measured worst phase noise is-115 dBc/Hz and-136 dBc/Hz at 100 Hz and 1 kHz respectively. |
