許多電信和計(jì)算應(yīng)用都需要一個(gè)能夠從非常低輸入電壓獲得工作電源的高效率降壓型 DC/DC 轉(zhuǎn)換器。高輸出功率同步控制器 LT3740 就是這些應(yīng)用的理想選擇,該器件能把 2.2V 至 22V 的輸入電源轉(zhuǎn)換為低至 0.8V 的輸出,並提供 2A 至 20A 的負(fù)載電流。其應(yīng)用包括分布式電源繫統(tǒng)、負(fù)載點(diǎn)調(diào)節(jié)和邏輯電源轉(zhuǎn)換。

Single-Ended and Differential S-Parameters Differential circuits have been important incommunication systems for many years. In the past,differential communication circuits operated at lowfrequencies, where they could be designed andanalyzed using lumped-element models andtechniques. With the frequency of operationincreasing beyond 1GHz, and above 1Gbps fordigital communications, this lumped-elementapproach is no longer valid, because the physicalsize of the circuit approaches the size of awavelength.Distributed models and analysis techniques are nowused instead of lumped-element techniques.Scattering parameters, or S-parameters, have beendeveloped for this purpose [1]. These S-parametersare defined for single-ended networks. S-parameterscan be used to describe differential networks, but astrict definition was not developed until Bockelmanand others addressed this issue [2]. Bockelman’swork also included a study on how to adapt single-ended S-parameters for use with differential circuits[2]. This adaptation, called “mixed-mode S-parameters,” addresses differential and common-mode operation, as well as the conversion betweenthe two modes of operation.This application note will explain the use of single-ended and mixed-mode S-parameters, and the basicconcepts of microwave measurement calibration.
