OSCILLATOR CIRCUIT WITH RECONFIGURABLE OSCILLATOR AMPLIFIER AND/OR HYBRID AMPLITUDE CALIBRATION CIRCUIT AND ASSOCIATED METHOD

摘要

An oscillator circuit (100) has a reconfigurable oscillator amplifier (110, 400). The reconfigurable oscillator amplifier (110, 400) is used to be coupled to a resonant circuit (102, R2) in parallel. The reconfigurable oscillator amplifier (110, 400) supports different circuit configurations for different operation modes, respectively. The reconfigurable oscillator amplifier (110, 400) has at least one circuit component shared by the different circuit configurations. The reconfigurable oscillator amplifier (110, 400) employs one of the different circuit configurations under one of the different operation modes.
