Abstract
An oscillator circuit configured to generate an output signal having a frequency comprising a current source, a trim circuit, and one or more capacitors. The current source may be configured to generate a temperature independent current in response to a first adjustment signal. The trim circuit may be configured to generate the first adjustment signal. The one or more capacitors may be configured to charge to a controlled voltage using the temperature independent current. The controlled voltage may regulate a variation of the frequency of the output signal.
