1 analog ic integrated circuit design company, was founded in 1998 by a group of engineers experienced in innovative power supply and management solutions 立?科技为专业之类比ic设计公司,成立于1998年,由一群拥有丰富类比ic设计经验以及具有专业创新能力的科技人才所组成。
Many famous analog ic companies offer a great number of white leds driving ics . according to the working principle, the driving ics can be classified into two types : in parallel and in series 在白光led驱动ic方面,各大模拟ic公司均推出了种类繁多的产品,这些产品可分为两类:并联型白光led驱动ic和串联型白光led驱动ic。
Corp . was founded in july 2000 . originally located in the tsing-hua university s business incubation center, it was successfully hatched in 2004 . it is now an r d company specializing in analog ic design 翔科技股份有限公司frontandtech.corp.于2000年7月成立,原本位于清华创新育成中心内,2004年孵育成功,离开自立,是一家以类比ic设计为主的研发公司。
The basic design index was : maximum output power 9w, no load consumption < 50 mw, switching frequency 132khz, maximum duty cycle 65 %, thermal shutdown temperature 135 . simulation is very important to analog ic design 该变换器电路的主要设计指标为:最大输出功率9w,空载时芯片的功耗低于50mw,开关频率为132khz,最大占空比为65%,热保护温度135。
A infrared system with which can detecte the pulse of human . because human body are semitransparent, and the transparence of it change along with the heart beat . the infrared sensor can detecte the change, we may tanslate the signal from sensor into a digital form by a cmos ic . when the signal change into a digital form, another ic can get the rhythm of the heart from the analog ic . this article designed the anologe ic which got the sensor signal into digital form 本论文完成了一个基于反射型红外线传感器的cmos模拟专用集成电路的设计,它构成的红外系统具有探测心跳频率的功能。设计根据人体组织的半透明度会随心脏跳动而变化的特点,由传感器探测到这一变化,通过专用集成电路将信号放大并利用,获得心跳频率。本模拟芯片结合数字电路可计算即时心率或统计心跳总数。
However, to the design of analog circuit, it is a challenge when its supply voltage is low o now the typical supply voltage of analog circuit is about 2.5-3 v, but the trend suggests it will be 1.5 v, even much lower . under this condition, great effort of research members domestic and abroad is devoted to the design of low-voltage circuit structure with standard cmos processes in the analog ic, one of the typical circuits is operational amplifier, and many analog circuits can use it . 然而,电源电压的下降对模拟电路的设计是一个挑战。如今模拟电路的典型电源电压大约是2.53伏,但是发展的趋势表明电源电压将是1.5伏,甚至更低。在这种情况下,国内外研究人员的很多精力花在设计适用于标准cmos工艺的低压电路结构。
In the analog ic, one of the typical circuits is operational amplifier . therefore, the design of low-voltage and low-voltage operational amplifier is very necessary . while realizing low-voltage and low-power, it must be noticed for the implementing of the main function of the circuit . because the low supply voltage affects performances of circuits, it is not very good for just implementing low-voltage and low power but not implementing the good performances 在模拟集成电路中,运算放大器是最典型的电路之一,所以设计低电压低功耗的运算放大器是非常必要的。在实现低电压低功耗的过程中,必须考虑电路的主要性能的实现,因为电源电压的降低将影响电路的性能,只是实现低压低功耗而不实现良好的性能是不大妥当的。
