Chapter 3 Offset-stabilized amplifiers 为了解决AZ离散时间的问题,TI的OPA335采用的multi-path的ping-pong结构,ping-pong其实就是两条AZ通路,一条在采用Vos另一条就作为信号通路,以实现信号传递的连续。OPA335的ping-pong作为低频通路,而信号恒在高频通路。 上图的ping-pong结构的voltage spike来自于Vb1在Va和Vc1...
失调稳态一种用来设计高精度运算放大器的技术。基本工作原理如下图所示。 Fig1 The concept of the offset-stabilized operational amplifier Gm2为主放大器,其失调为Vos。Gm4假想为是一个零失调的运放,它用来对Gm2的Vos进行处理。Gm3可以看作主放大器的辅助输入。Gm4在Gm3输入端产生一个输入电压,Gm3再产生一个...

In this paper, an offset-stabilized operational amplifier is described. The amplifier employs a chopper amplifier in a low frequency path to cancel the offset of a wide-bandwidth amplifier. A sample-and-hold circuit is used to reduce the chopper ripple, and the low frequency path is also offs...
In this near-degeneracy region, a beat at the offset between the signal and idler frequency combs is detected. Phase-locking this beat to an external reference stabilizes the spectral envelopes of the signal- and idler output. At the same time, the underlying frequency combs are stabilized ...

The laser system consisted of two phase-locked extended-cavity diode lasers with a frequency offset of 9.2 GHz, whose intensity was also stabilized using an acoustooptic modulator. The power concentration and the intensity stability were 93% and 0.1%, respectively....
An intermittent frequency offset lock of a transverse Zeeman laser to an iodine stabilized He-Ne laser We proposed a modulation-free, high power frequency standard laser utilizing a three-mode stabilized He-Ne laser of 2 mW output (3MSL) and an iodine stabilized He-Ne laser (l2SL). Frequenc...
