The hybrid-pi model considered so far assumes that the incremental output resistance of a bipolar transistor is infinite. However, this is not the case, as anyone can attest to who has looked at ...

It's been about 40 years since the first monolithic op amps were introduced. Those first devices, some of which are still in production, were designed exclusively in bipolar technology. Today most ...

Digital to analog convertors (DACs) are devices that convert digital, typically binary signals to outputs in the form of voltage. The voltage generated can then be used to produce light, as in video ...

In order to achieve useful amplification from a transistor, the transistor is generally biased in the forward-active region (FAR). The FAR is the region of operation of the transistor where ...

Op Amps Continue To Flourish Since the introduction of the first monolithic bipolar operational amplifier (op amp) in the mid-sixties by Fairchild Semiconductor (www.fairchildsemi.com), the technology ...

What is driving the power vs. performance tradeoffs? How to improve the op-amp bandwidth-to-power ratio. How noise, distortion, and other factors impact the power/performance design decisions. The ...

Members can download this article in PDF format. Use of differential signaling in analog front ends is increasing across a range of applications, from audio processing to factory automation.

I am not sure how “fashionable” discrete transistor design is nowadays, but anyone using discrete transistors, bipolar or otherwise, for high speed designs other than for switching probably knows ...
