OPTOELECTRONICS CIRCUIT COLLECTION
AVALANCHE PHOTODIODE BIAS SUPPLY 1Provides an output voltage of 0V to +80V for reverse biasingan avalanche photodiode to control its gain. This circuit canalso be reconfigured to supply a 0V to –80V output.LINEAR TEC DRIVER–1This is a bridge-tied load (BTL) linea ...
单片机编程 Emulating a synchronous serial
The C500 microcontroller family usually provides only one on-chip synchronous serialchannel (SSC). If a second SSC is required, an emulation of the missing interface mayhelp to avoid an external hardware solution with additional electronic components.The solution presented in this paper and in the a ...

技术资料 基于51单片机的温室自动灌溉系统设计
目前在温室中使用广泛的灌溉系统多为人工控制灌溉系统,不仅容易造成资源浪费,而且可能因不适量浇灌或停止浇灌不及时导致农作物枯死或溺亡,造成极大的经济损失。针对这一问题,本文设计了一个基于单片机的温室自动灌溉系统。该系统以AT89C51单片机及其外围电路作为控制部分的主机电路,采用YL-69土壤湿度传感器作为检测温室条 ...
模拟电子 DAC技术用语 (D/A Converters Defini
Differential Nonlinearity: Ideally, any two adjacent digitalcodes correspond to output analog voltages that are exactlyone LSB apart. Differential non-linearity is a measure of theworst case deviation from the ideal 1 LSB step. For example,a DAC with a 1.5 LSB output change for a 1 LSB digital codec ...
