    • Techniques and structures for tunign integrated, distributed voltage-controlled oscillators (DVCO'S) across a wide microwave frequency range are disclosed. One type of DVCO implements a tunign circuit that includes a pair of interconnected amplifying transistors and a current source connected to the transistors, such that a differential voltage input to the circuit adjusts the current to eact transistor and effectively adjusts the "eletrical lenght" of one of the transmission lines on which the output frequency is oscillating. This, in turn, adjusts the time delay and thus frequency of the signal propagating on the lines across a wide frequency band. This technique is called "current-steering." In a preferred embodiment, the tuning circuit is balanced with a complementary tuning circuit to effectively adjust the electrical lenght of the second transmission line in the oscillator. In another technique that provides for more coarse, but wider range, broadban frequency tuning, the time delay, and thus frequency, of the DVCO is adjustable by varying the capacitive loading on the transmission lines, by introducing a coupling capacitor between the transmission lines and tuning the intrinsic capacitances of the gain transistors with a dc bias input.

    • It is disclosed a microwave VCO implemented in planar way technique on the same standard glass reinforced FR4 substrate supporting the layout of the relevant control circuit (in particular, locking circuits and bias circuits) operating at a well lower frequency. The area occupied by the VCO on the standard glass reinforced FR4 substrate is very small, minimizing by this the power loss of the microwave oscillation during its propagation. To this purpose, the varactor is placed in close contact with the active element (GaAsFET) of the VCO, which therefore does not include the traditional resonant cavity. The use of stubs in critical points of the circuit prevents the loss of power otherwise introduced by impedance mismatch. Through these measures, the VCO oscillation frequency can be driven up to 18 GHz, without altering by that the operation characteristics of the same at a significant extent. Moreover, since the Applicant has not recorded a significant electromagnetic interference in the substrate areas, close to the VCO, it does not require as well appropriate shielding means. Thanks to the invention, it is thus possible to use the same manufacturing process to obtain both the VCO layout and the layout of the above mentioned low frequency.
    • 公开了在相同的标准玻璃增强FR4基板上以平面方式技术实现的微波VCO,其支持以较低频率工作的相关控制电路(特别是锁定电路和偏置电路)的布局。 在标准玻璃FR4基板上的VCO所占据的面积非常小,从而最小化了微波在其传播过程中的功率损耗。 为此,变容二极管与VCO的有源元件(GaAsFET)紧密接触,因此,其不包括传统的谐振腔。 在电路的关键点使用短截线可防止由于阻抗失配导致的功率损失。 通过这些措施,VCO振荡频率可以驱动高达18 GHz,而不会在很大程度上改变其运行特性。 此外,由于申请人没有在靠近VCO的衬底区域中记录到显着的电磁干扰,所以不需要合适的屏蔽装置。 由于本发明,因此可以使用相同的制造工艺来获得上述低频的VCO布局和布局。

    • An inductance enhanced rotary traveling wave oscillator is disclosed. Portions of the transmission line conductors are increased in length and run in parallel. Because the currents in these portions travel in the same direction, the inductance of these inductors is increased. By controlling the length of the transmission line conductors in these areas compared to the lengths in which the currents travel in opposite directions, the overall impedance of the oscillator can be increased. Increased impedance leads to lower power, higher Q, and lower phase noise for the oscillator. Additionally, the folded nature of the transmission line conductors permits a longer length of transmission line conductors to be routed in a smaller area. The folded nature also permits placement of the devices to take into account their switching delays. A folded circular version of the oscillator is possible, leading to improved access to phase taps on the oscillator.
    • 公开了一种电感增强型旋转行波振荡器。 传输线导体的部分长度增加并行。 因为这些部分的电流在相同的方向上行进,所以这些电感器的电感增加。 通过控制这些区域中的传输线导体的长度与电流沿相反方向行进的长度相比,可以增加振荡器的整体阻抗。 增加的阻抗导致振荡器的功率更低,Q更高,相位噪声更低。 此外,传输线导体的折叠性质允许更长的传输线导体在较小的区域中布线。 折叠的性质还允许设备的放置以考虑其切换延迟。 振荡器的折叠圆形版本是可能的,从而改善了对振荡器的相位抽头的访问。
