查询词典 charge carrier

First it changed the variety of capacitive into the variety of voltage by charge amplifier ,then demodulates the carrier wave signal modulated by the accelerometer signal and passed thought the low pass filter ,at last ,output a direct current signal which is directly proportional the accelerometer signal ,the circuit has the function of measuring the variety of capacitive and the specialties of higher sensitive and better linearity.

介绍一种可用于微机械电容式加速度计检测的接口电路，该电路利用电荷放大器把电容变化转变成电压变化，再对被加速度信号调制的载波信号进行解调，经过低通放大滤波，最后得到与加速度信号成正比的直流电压信号，具有测量差分电容变化的功能和灵敏度高、线性好的特点。

Major shipping companies to contractors, international air transport operations for the import and export of the main charge of Booking, storage, transit, containers assembled uncrating, customs and related short inland transport or rail carrier, omnidirectional, and provide various forms of delivering supply chain tracking service.

Since Al〓Ga〓In〓P possesses larger valence band difference to GaAs and wider energy gap, minor carrier reverse injection from base and space charge region recombination in the emitter are effectively suppressed in Al〓Ga〓 In〓P/GaAs HBT. Under most circumstances, quasi-neutral base recombination current dominates the base current, and its ratio to collector current varies little with collector current and temperature, thus greatly stabilizes the current gain.

Al〓Ga〓〓In〓P/GaAs HBT由于异质结的△Ev较大，发射区禁带较宽，有力地抑制了基区少子反向注入流和发射区空间电荷区复合电流；在大多数情况下，基极电流以准中性基区复合电流为主，其与集电极电流的比值随集电极电流和温度的变化极小，稳定了电流增益。
