摘要： A local oscillator communicates a signal of relatively low frequency across an integrated circuit to the location of a mixer. Near the mixer, a frequency-multiplying SubHarmonically Injection-Locked Oscillator (SHILO) receives the signal and generates therefrom a higher frequency signal. If the SHILO outputs I and Q quadrature signals, then the I and Q signals drive the mixer. If the SHILO does not generate quadrature signals, then a quadrature generating circuit receives the SHILO output signal and generates therefrom I and Q signals that drive the mixer. In one advantageous aspect, the frequency of the signal communicated over distance from the local oscillator to the SHILO is lower than the frequency of the I and Q signals that drive the mixer locally. Reducing the frequency of the signal communicated over distance can reduce power consumption of the LO signal distribution system by more than fifty percent as compared to conventional systems.
摘要翻译：本地振荡器将跨越集成电路的相对较低频率的信号传送到混频器的位置。在混频器附近，倍频次谐波注入锁定振荡器（SHILO）接收信号并从中产生较高频率的信号。如果SHILO输出I和Q正交信号，则I和Q信号驱动混频器。如果SHILO不产生正交信号，则正交发生电路接收SHILO输出信号并从其产生驱动混频器的I和Q信号。在一个有利的方面，从本地振荡器到SHILO的距离传递的信号的频率低于驱动混频器的本地I和Q信号的频率。与常规系统相比，降低信号传输距离的频率可以将LO信号分配系统的功耗降低50％以上。

摘要： A frequency divider involves a plurality of Injection-locked Ring Oscillators (ILRO). A first ILRO includes a pair of cross-coupled N-channel transistors, a pair of load resistors, an integrating capacitor, and a current injection circuit. The drain of each transistor is coupled to the gate of the other transistor. Each load resistor couples the drain of each transistor to a circuit voltage source. The integrating capacitor couples the sources of each transistor. The current injection circuit alternately opens and closes a path from the source of each transistor to circuit ground in response to an oscillatory input signal of a first frequency. In response, the voltage state at the drain of each transistor is alternately latched and toggled, generating a differential pair of oscillating signals frequency divided by two. A first and second ILRO driven in antiphase generate two differential output signals in phase quadrature.

摘要： Microelectronics have now developed to the point where radiation within the terahertz frequency range can be generated and used. Here, an integrated circuit or IC is provided that includes a phased array radar system, which uses terahertz radiation. In order to accomplish this, several features are employed; namely, a lower frequency signal is propagated to transceivers, which multiplies the frequency up to the desired frequency range. To overcome the losses from the multiplication, an injection locked voltage controlled oscillator (ILVCO) is used, and a high frequency power amplifier (PA) can then be used to amplify the signal for transmission.

摘要： A crystal oscillator-based module, which includes a crystal resonator receiving a conditioned signal from a first bus and passing a resonator signal to a sustaining stage amplifier. A synchronization range expansion circuit is connected between a gain control network and the resonator. A tri-state buffer has a main input connected to receive the resonator signal through a buffer. The output of the tri-state buffer is connected to a second bus, through a matching network if necessary. A synchronous clock system can be formed by connecting these modules alternately to the two busses. The tri-state buffer also has a control input, which may be connected to a delay circuit between Vcc and ground, so as to allow hot swapping and for other benefits.

摘要： An injection-locked oscillator circuit includes a master oscillator, a slave oscillator, and an injection lock control circuit. The slave oscillator is decoupled from the master oscillator (for example, due to an unlock condition). When the slave is free running, its oscillating frequency is adjusted (for example, as a function of a supply voltage). After an amount of time, the slave is to be relocked to the master (for example, due the unlock condition no longer being present). The slave oscillating frequency is made to be slightly lower than the master oscillating frequency. The slave is then only recoupled to the master upon detection of an opposite-phase condition between the master oscillator output signal and the slave oscillator output signal. By only recoupling the slave to the master during opposite-phase conditions, frequency overshoots in the slave oscillating frequency are avoided that may otherwise occur were the recoupling done during in-phase conditions.
