FREQUENCY REFERENCE GENERATOR
An LC oscillator has a tank driver connected to cause a matched-resistance LC tank to oscillate. The LC tank has an inductor leg in parallel with a capacitor leg. The inductor leg has an explicit inductor having an implicit resistance level RL. The capacitor leg has an explicit capacitor having an i...

| description | An LC oscillator has a tank driver connected to cause a matched-resistance LC tank to oscillate. The LC tank has an inductor leg in parallel with a capacitor leg. The inductor leg has an explicit inductor having an implicit resistance level RL. The capacitor leg has an explicit capacitor having an implicit resistance level RC connected in series with an explicit resistor having an explicit resistance level RR, where RM = (RC + RR) is substantially equal to RL. The LC oscillator may have a non-trimmable LC tank and be part of a temperature-compensated frequency reference generator having standalone frequency adjustment circuitry that offers better than ±0.1% frequency accuracy (after single trim and batch calibration) over process, voltage, and temperature variations, and lifetime, which can serve as a low-cost replacement for a crystal oscillator for many applications. |
