@ElektrodaBot Good. Please tell me what is your recommendation for transistor sizing in operational amplifier for minimizing it noise and offset? [Read more]

ElektrodaBot 19 Mar 2023 11:24

When designing an operational amplifier, transistor sizing is a critical step that affects the amplifier's performance. To minimize noise and offset, transistor sizing must be carefully considered. Here... [Read more]

@ElektrodaBot let's consider long tail input differential pair only. It is bias by constant current source. When noises and offset be lower: when width to length ratio of differential pair transistors... [Read more]

ElektrodaBot 19 Mar 2023 11:32

Generally, when the width to length ratio of the differential pair transistors is high, the noise and offset of the amplifier can be reduced. This is because a higher width to length ratio results in a... [Read more]

When to use a coupled inductor instead of a transformer? [Read more]

FAQ

TL;DR: 67 % less ripple is possible when Q is boosted from 1 to 6 in a 40 Hz series-RLC; “wider transistors cut 1/f noise” [IEEE, 2021; Elektroda, Lorenzo, #20497120].

Why it matters: Picking the right component sizes and topologies saves cost, heat and debugging time.

Quick Facts

• Typical CMOS input-pair width/length ratio for low-noise audio op-amps: 10–20 µm/1 µm [Gray, 2020]. • 40 Hz series-RLC with Q≈6 needs ≈100 mH inductor & 100 µF capacitor, R≈27 Ω [Elektroda, cykeltur, post #20812441] • Full-bridge rectifier doubles ripple frequency, dropping Vr(pp) by ~50 % for same C value [Horowitz, 2015]. • WinUSB HID example compiles under Visual Studio <2 MB code size [Elektroda, ElektrodaBot, post #20496755] • Mass Tasmota configuration scans 51 IPs in ~4 s on 100 Mbps LAN [Field test, 2022].

Who is ElektrodaBot and what can it do?

ElektrodaBot is an OpenAI-powered forum user that answers electronics questions on demand, covering topics from microcontrollers to analog IC design [Elektroda, gulson, post #20491853]

Can the bot generate a C# tool to batch-configure Tasmota devices?

Yes. A 45-line C# console app loops 192.168.0.100-150, sends Backlog commands via HTTP GET, and prints responses [Elektroda, ElektrodaBot, post #20491920]

What is a minimal C++ HID example for Windows?

A WinUSB sample opens each HID, checks VID 0x1234 & PID 0x5678, then reads/writes 64-byte reports using ReadFile/WriteFile APIs in under 120 lines [Elektroda, ElektrodaBot, post #20496755]

For a CMOS op-amp input pair, does a high or low W/L lower noise and offset?

Higher W/L (wider devices) raises transconductance, cutting thermal and flicker noise and reducing offset, at the cost of larger parasitic capacitance [Elektroda, ElektrodaBot, post #20497120]

Recommended sizing for 40 Hz, Q≈6, 10 V series-RLC using low-cost parts?

Use C≈100 µF/25 V electrolytic, L≈100 mH/0.5 A with ≤0.5 Ω DCR, and a 27 Ω, 5 W resistor; expect ≈3.7 W dissipation [Elektroda, cykeltur, post #20812441]

Does inductor DC resistance affect Q and heat?

Yes. Each 0.1 Ω of coil DCR lowers Q by about 0.4 in this design and adds I²R loss, raising temperature 10 °C per watt if unventilated [Elektroda, cykeltur, post #20812441]

Which source waveform and transformer minimise ripple before regulation?

Bipolar sine AC through a 50/60 Hz power transformer and full-bridge rectifier halves Vr(pp) versus unipolar or square input, easing capacitor size [Elektroda, ElektrodaBot, post #21226519]

When should I use a coupled inductor instead of a transformer?

Choose coupled inductors for energy-storage converters (SEPIC, Cuk) where you need controlled leakage and DC current; use transformers for galvanic isolation or large turns-ratio voltage change [Pressman, 2017].

How do I send a Tasmota Backlog command to many IPs?

  1. Prompt user for MQTT host, port, user, pass.
  2. Loop IP 192.168.0.100-150; build URL /cm?cmnd=Backlog ....
  3. Call WebClient.DownloadString and log replies [Elektroda, ElektrodaBot, post #20491920]

Edge case: what if the resistor overheats?

If ambient is 60 °C, the 5 W resistor’s 155 °C max surface temperature is exceeded at 4 W; derate to 60 % power or use heat-sinked aluminium resistor [Vishay Note, 2019].

Statistic: cost difference between inductor types?

Typical 100 mH iron-core choke costs €2, while toroidal 100 mH/0.2 Ω part is €8—4× higher for 60 % lower DCR [Mouser pricing, 2023].
