    Abstract: A monolithic high frequency voltage controlled oscillator trimming circuit includes a plurality of capacitance loops (140) selectively connected between a first (120) and second (130) differential input of a voltage oscillator active network (110). A plurality of diodes (159, 160), connected in series with the respective plurality of capacitance loops (140), selectively connect respective capacitance loops (140) between the first (120) and second (130) differential input when forward biased. In a similar fashion, the plurality of diodes (159, 160) selectively disconnect the respective capacitance loops (140) from the first (120) and second (130) differential input when reverse biased. A controller (180) applies a forward biasing voltage to the diode (159, 160) of the selected capacitance loop (140) to connect the capacitance loop (140) to the active network (110) of the voltage controlled oscillator and applies a reverse biasing voltage to the diode (159, 160) of the selected capacitance loop (140) to disconnect the capacitance loop (140) from the active network (110). The diodes (159, 160) used in the capacitance loops (140) form a switch operable at high frequencies and are formed from a bipolar complementary metal oxide semiconductor electro-static discharge protection diode.

    Abstract: In a differential oscillator means (535, 553, 521, 523, 549 and 551) are provided for making it possible to band switch the oscillator. This is obtained by means of cross connecting two transistors (501 and 503) and connecting inductors (509 and 511) to the transistors (501 and 503). The oscillator can be band switched by means of shortening a circuit comprising of two diodes (521 and 523). The switching time for the oscillator is very short since the oscillating circuit does not comprise any serially connected capacitors. In addition all frequency bands of the oscillator can be made impedance matched by means of adding an additional pair of varactor diodes (529 and 531).

    Abstract: Apparatus and methods are also disclosed related to an oscillator that includes a switching network configured to tune a resonant frequency of a resonant circuit. One such apparatus includes a switching network having a circuit element, such as a capacitor, that can be selectively coupled to the resonant circuit by a switch, such as a field effect transistor. For instance, the switch can electrically couple to circuit element to the resonant circuit when on and not electrically couple the circuit element to the resonant circuit when off. An active circuit can assert a high impedance on an intermediate node between the switch and the circuit element when the switch is off.

A center tap 19 is formed in a strip-line 16 of a resonator. A switching element 20 is connected to the center tap 19, and this switching element 20 is turned ON, so that the center tap is shortcircuited to the ground so as to vary the oscillating frequency. A slit A1 is conducted in the vicinity of the center tap 19 along the strip-line 16 and directed toward a shortcircuited end 17 of the strip-line, so that a frequency shift amount is adjusted. Also, a slit B1 is conducted in the vicinity of the shortcircuited end 17 along the strip-line 16 and directed toward the center tap 19, so that a frequency shift amount is adjusted. Also, trimming points are provided on the side of a hot terminal 18 from the center tap 19, and also provided on the side of the shortcircuited end 17 from the center tap 19, and further a slit is conducted along an intersecting direction of the strip-line 16, so that a shift amount is adjusted.
