Abstract: A local oscillator generator (LO generator) may be configured to transmit an LO signal to a mixer. The LO generator may include an input buffer configured to generate a first internal oscillator signal based on the input oscillator signal. The LO generator may include a frequency dividing circuit configured to generate a second internal oscillator signal based on dividing a frequency of the first internal oscillator signal. The LO generator may include an output buffer configured to generate the LO signal based on the second internal oscillator signal. The input buffer and the frequency dividing circuit may each be configured to receive a power voltage independently of the output buffer.
