Abstract: A calibration device, method and electronic device using the same provided by embodiments of the present disclosure only need to measure frequency values of two temperatures, then calculate frequency drift rates of various configuration combinations, and select the configuration combination with the smallest frequency drift rate to set configuration values of a trimming module. Thus, the test time can be reduced. In one embodiment, a simple heating device can be directly disposed on the chip package structure of the electronic device, so it is not necessary to use an external heating device for heating, and the environmental space required for placing the external heating device can be reduced.

A neural network processing module includes one or more neurons which receive one or more inputs corresponding to a parameter of an electronic oscillator, such as temperature. Weights are calculated and applied to inputs to the neurons of the neural network as part of a training process, wherein the weights help shape the output of the neural network processing module.

Abstract: A resonator of a VCO includes a fine tuning main varactor circuit, an auxiliary varactor circuit, and a coarse tuning capacitor bank circuit coupled in parallel with an inductance. The main varactor circuit includes a plurality of circuit portions that can be separately disabled. Within each circuit portion is a multiplexing circuit that supplies a selectable one of either a fine tuning control signal (FTAVCS) or a temperature compensation control signal (TCAVCS) onto a varactor control node within the circuit portion. If the circuit portion is enabled then the FTAVCS is supplied onto the control node so that the circuit portion is used for fine tuning. If the circuit portion is disabled then the TCAVCS is supplied onto the control node so that the circuit portion is used to combat VCO frequency drift as a function of temperature. How the voltage of the TCAVCS varies with temperature is digitally programmable.
