Abstract: A method for scaling (reducing or enlarging) electronic device symbols operates on an input file (ie. body file) of information in precoded characteristics representing the electronic device symbol. The characteristic has a plurality of parameters describing it. The method, performed by a computer, first parses a plurality of parameters associated with the characteristic. Certain parameters are selected and scaled by the method. Lastly, the scaled parameters are reassembled along with the non-scaled parameters in the same characteristic and replaced in the body file of information.

Abstract: An oscillator including an active device (38), a surface acoustic wave resonator (40) connected in a feedback relationship to the active device and an impedance matching circuit is disclosed. The impedance matching circuit in one arrangement is an output impedance matching circuit including an inductor (46) connected in the feedback loop to the output of the active device. In another arrangement, the impedance matching network is an input impedance matching network including an inductor (42) connected in the feedback loop to the input of the active device. In another arrangement of the invention, a varactor diode (60) is connected in the feedback loop and is controlled by a reverse voltage which changes the capacitance of the diode, adjusting the frequency of the oscillator.
