在一些对运放slew rate要求高的应用中,比如高速运放,AD/DA等,我们需要很高的slew rate。通常我们可以通过调整输入级静态电流、补偿电容大小来满足slew rate,这只是最常规基本的办法。除此之外,我们可以借助辅助电路来实现slew rate提升。以下展开分析一篇非常实用的slew rate boost电路。 Fig 1 带有slew rate boost电路...

Then, a technique for slew-rate (SR) boosting in switched-capacitor circuits is proposed in the order to be utilized in the proposed 12-bit pipelined ADC. This technique makes use of a class-B auxiliary amplifier that generates a compensating current only when high slew-rate is demanded by ...
An IO driver utilizes a slew rate boost circuit coupled to an IO driver circuit to improve the slew rate of the driver during transitions on the output of the driver. One or more additional output stages are coupled in parallel with a primary output stage of the driver, and are temporarily...

In this work, a high gain and high bandwidth rail-to-rail operational amplifier with slew rate boost circuit is presented. The constant gm is enhanced through a source-to-bulk bias control of an input pair. A source degeneration scheme is applied to realize an input common-mode range insensi...
CMOS SR/SR[max] Versus VID For the TLV9001, 100% of the maximum natural slew rate occurs with VID >> 100mV. However, the internal bias current (B) and CC capacitor give 0.5V/µs slew rate, not the 2V/µs stated in the data sheet. The TLV9001 employs a slew boost circuit ...
For example, the paper's results show that 100% of a device's maximum slew rate can be achieved with as little as 0.1V input, whereas the OPA690 needs around 2V. This is common in amplifiers with slew rate boost. Although the slew rate decreases more steeply with decreases in VID, ...
