具備處理外部模擬信號(hào)功能是很多電子設(shè)備的基本要求。為了將模擬信號(hào)轉(zhuǎn)換為數(shù)字信 號(hào),就需要藉助A/D 轉(zhuǎn)換器。將A/D 功能和MCU 整合在一起,就可減少電路的元件數(shù)量和 電路板的空間使用。 HT45F23 微控制器內(nèi)建6 通道,12 位解析度的A/D 轉(zhuǎn)換器。在本應(yīng)用說(shuō)明中,將介紹如何 使用HT45F23 微控制器的A/D 功能。

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frequency of operationincreasing beyond 1GHz, and above 1Gbps fordigital communications, this lumped-elementapproach is no longer valid, because the physicalsize of the circuit approaches the size of awavelength.Distributed models and analysis techniques are nowused instead of lumped-element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.

一個(gè)LCD燈的小程序。不是我寫(xiě)的。我只負(fù)責(zé)了調(diào)試。適用在ACEXEP1K30QC208-3上。我跑了SIMULATOR,管腳連接標(biāo)示了。我也下在電路板上試過(guò)了,沒(méi)有問(wèn)題。要用到實(shí)驗(yàn)板上的兄弟們把CLK1改到TESTOUT3或者0就好了。綫幫助新手,人人有責(zé)。
