Abstract:
1. A method, comprising: utilizing an electronic device including a first substrate carrying a voltage controlled oscillator circuitry and a second substrate carrying inductance adjustment circuitry, the voltage controlled oscillator circuitry including a first inductor and the inductance adjustment circuitry including a second inductor; electromagnetically coupling the first inductor and the second inductor to provide a mutual inductance therebetween; during the coupling of the first inductor and the second inductor, operating the voltage controlled oscillator circuitry with a first frequency range determined as a function of the mutual inductance; with the inductance adjustment circuitry, changing operation of the second inductor to alter the mutual inductance between the first inductor and the second inductor; and operating the voltage controlled oscillator circuitry with a second frequency range different than the first frequency range after the operation of the second inductor is changed.
