Talk:Buffer amplifier

The small-signal parameters for the current follower are to be added shortly. Brews ohare 23:36, 2 December 2007 (UTC)

Transistor examples

The new section on practical buffers is useful, but I feel the material is better suited for the main common collector and common base articles. I think a link to those articles would be sufficient, instead of getting into all they detailed equations and equivalent circuits here. -Roger 23:55, 2 December 2007 (UTC)

Hi Roger: Thanks, I'll look at those links. Meanwhile, can you help me with FIgure 5? I uploaded a new version to the commons, but the article itself doesn't show the new version. If I double-click on the figure, the updated version does show up. Maybe you can tell me how to avoid this problem?? Brews ohare 05:13, 3 December 2007 (UTC)

Hi Brews. Weird the thumbnail doesn't match the full image. Its probably just a Wikipedia issue, I'd wait and see if it fixes itself. BTW there's a nice online schematic editor at http://mysite.verizon.net/negatron/klunky/klunky.html that I use for all my schematics. -Roger 05:40, 3 December 2007 (UTC)

I undertook to follow your suggestion; see what you think. Tnx. Brews ohare 20:36, 4 December 2007 (UTC)

Chart of Single-Transistor Amplifiers - FET type: MOSFET or JFET?

In the section “Chart of Single-Transistor Amplifiers”, the example circuit with a FET has a column title indicating a MOSFET, but the figure uses the JFET symbol. Also, the image's page name N-channel_JFET_common_source.svg

confirms it is a JFET.

Can a MOSFET be used to create a single-transistor amplifier as well? If so, could someone add examples showing MOSFET use in addition to JFET use? --Colinb (talk) 17:49, 23 November 2011 (UTC)

The figures (except figure 5) use the JFET symbol. When using MOSFETs the circuit is essentially the same, only the DC level is usually a little different.--91.3.73.89 (talk) 12:07, 7 July 2012 (UTC)

Examples of buffer amplifiers in discrete packages

Are there any other devices available than LM110/LM210/LM310 ? Seems like useful enough functionality to supply as a discrete device, for labs, breadboards, etc. — Preceding unsigned comment added by 125.253.44.20 (talk) 10:04, 30 July 2013 (UTC)

Voltage buffer

In this section, it's good to add a block diagram image.--Diraniyoussef (talk) 19:32, 17 January 2021 (UTC)

Voltage buffer vs. Current Buffer

Right in the first sentence (the definition) of the voltage buffer and the current buffer, when we speak about the impedance of first circuit and the impedance of the second circuit, isn't it better to clarify that the two impedances are considered in series for the voltage case and in parallel for current buffer ? I think this very simple clarification is useful.--Diraniyoussef (talk) 20:19, 17 January 2021 (UTC)

Introduction

What's the meaning of this : "by whatever currents (or voltages, for a current buffer) that the load may be produced with" ?--Diraniyoussef (talk) 20:56, 17 January 2021 (UTC)
