Abstract: An RF peak-detector circuit can operate over a wide range and can compensate or correct an output voltage error term that depends on the thermal voltage and the input signal voltage. At or near a minimum value of the input signal voltage range, such compensation can include a scaled base-emitter ratioing of bipolar junction transistors used to generate the output voltage, each of which can be biased by a primary current. At or near a maximum value of the input signal voltage range, this can include using an auxiliary bias current circuit that can shift auxiliary bias current between these bipolar junction transistors. The auxiliary bias current circuit can include scaled bipolar junction transistors in a cross-coupled configuration and an equivalent resistance circuit between emitters of the cross-coupled BJTs. This can provide a robust approach for improving the accuracy of an RF peak-detector circuit over a wide range.

Abstract: The present invention provides a METHOD TO CALCULATE AN ENERGY EFFICIENCY RATING for information technology equipment. This method specifically pertains to information technology equipment that doubles its capabilities in a predetermined timeframe according to Moore's Law. This method uses a formula to calculate an energy efficiency rating based on power consumption and transactions per second. It further calculates a normalized rating where the absolute rating is adjusted based on Moore's Law prediction of improvements. As a result the method invented is the first and only method to compare information technology from various generations of hardware, processor and component architecture with each other in terms of their energy efficiency.

Abstract: This invention describes a method by which the output power of a circuit or system at any point can be efficiently and cost effectively sampled in a simple and broadband fashion for processing in a closed loop system for applications such as power level control in very broadband circuits. A divider circuit consisting of a selection of passive lumped elements is used to create a very broadband means of sampling the RF power level at any point in a transmission line. Unlike prior art schemes of this nature, this circuit does not rely upon extremely accurate element values and minimization of parasitic reactances. Used in conjunction with a balanced detector-logarithmic or other amplifier combination this invention result in a very broadband low cost simplified realization of the traditional costly bandwidth limited directional coupler-detector combination.
