Abstract: A frequency conversion system with improved performance. In one embodiment an image reject mixer is used to perform frequency conversion providing an initial degree of suppression of the image and local oscillator leakage signals, and a signal to noise enhancer (SNE) is used to further suppress the image and local oscillator signals, the signal to noise enhancer being a nonlinear passive device that attenuates low-power signals while transmitting high power signals with little loss. The signal to noise enhancer may be fabricated as a thin film of yttrium iron garnet (YIG) epitaxially grown on a gadolinium gallium garnet (GGG) substrate, the GGG substrate secured to a microwave transmission line from the input to the output of the signal to noise enhancer, such that the thin film of yttrium iron garnet is close to the transmission line.

Abstract: A correlation between noise injection time at which a power supply noise signal is applied to a clock path and a path delay of the clock path at the time of the power supply noise signal being applied is acquired. Furthermore, noise injection time width based on a clock signal inputted from a circuit arranged before the clock path to the clock path is set. The differences between path delays within the set noise injection time width are calculated by the use of the acquired correlation and the maximum value of the differences is estimated to be clock jitter of the clock path. The estimated clock jitter is smaller than the worst value and overestimation is prevented.

Abstract: A method is for rejecting spurs within a chip containing analog and digital functions. The spurs may be timed by a clock signal derived from the output frequency of a high frequency phase locked loop. Original analog rejection bandwidths associated with operation of analog functions may be determined, and then original spurs associated with operation of the digital functions and capable of directly or indirectly affecting the original analog rejection bandwidths may be identified. A final analog rejection bandwidth may be determined based on the original analog rejection bandwidths, and final spurs may be obtained based on the original spurs. A frequency shift of the output frequency of the high frequency phase locked loop to effectuate a rejection of the final spurs from the final analog rejection bandwidth may be determined, and the high frequency phase locked loop may be controlled to shift the output frequency by the frequency shift.

Abstract: A method for transmitting and/or receiving a potential aggressor audio signal includes a transmission and/or a reception of successive groups of data timed by a first clock signal within respective successive frames synchronized by a second clock signal. In the presence of a risk of interference of the potential aggressor audio signal with a different, potential victim, signal, during the transmission or reception of the potential aggressor audio signal, the frequency of the first clock signal is modified while keeping the frequency of the second clock signal unchanged.

Abstract: Systems and methods for reducing interference caused by leakage of signals generated by a spread spectrum phase lock loop (SS PLL). The system and method uses a sinusoidal spreading signal to spread the output of a SS PLL. A notch filter tracks the frequency of the output of the SS PLL to steer the notch in the filter to the instantaneous frequency output from the SS PLL, thus allowing the notch filter to be placed in the path of signals that have unwanted leakage from the SS PLL.
