Measuring power with logic: a cost-effective technique

Simplifying power measurement with logic? There's a cost-effective technique for measuring active power using isolated ADCs and a single XNOR logic gate, eliminating the need for an analog multiplier or microcontroller. Check out this new article by my colleague Dan Tooth, where he converts voltage and current signals to digital bitstreams that can be multiplied through a basic XNOR gate. #analogdesign #engineering #powerelectronics #SignalChainBasics

Power electronics is rapidly evolving, with growing demand for smarter, more efficient, and scalable power supplies. Digital control offers these benefits but has struggled in the 50 W–1 kW range due to the cost and power needs of microcontrollers, leaving analog control dominant but limited. This article shows how ROHM’s LogiCoA™ overcomes that gap by combining analog efficiency with digital flexibility—making advanced control practical for mainstream industrial equipment. It reviews current limitations, introduces the hybrid approach, and highlights the gains in cost, performance, and design freedom.

Among them, the BJT (Bipolar Junction Transistor) and FET (Field Effect Transistor) are the two most common types. Both are widely used for amplification and switching, but they differ in structure, control, and applications. 💬 𝐁𝐉𝐓 (𝐁𝐢𝐩𝐨𝐥𝐚𝐫 𝐉𝐮𝐧𝐜𝐭𝐢𝐨𝐧 𝐓𝐫𝐚𝐧𝐬𝐢𝐬𝐭𝐨𝐫) - 𝐂𝐡𝐚𝐫𝐚𝐜𝐭𝐞𝐫𝐢𝐬𝐭𝐢𝐜𝐬 + A current-controlled device. + Uses both electrons and holes → bipolar device. + Requires a Base current to operate. + Has low input impedance. + Consumes more power due to continuous Base current. - 𝐀𝐝𝐯𝐚𝐧𝐭𝐚𝐠𝐞𝐬 + Provides high current gain. + Suitable for low-voltage circuits. + Better linearity in analog signal amplification. - 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 + Analog amplifiers (audio, RF, instrumentation). + Signal processing circuits. + Low-power switching applications. 💬 𝐅𝐄𝐓 (𝐅𝐢𝐞𝐥𝐝 𝐄𝐟𝐟𝐞𝐜𝐭 𝐓𝐫𝐚𝐧𝐬𝐢𝐬𝐭𝐨𝐫) - 𝐂𝐡𝐚𝐫𝐚𝐜𝐭𝐞𝐫𝐢𝐬𝐭𝐢𝐜𝐬 + A voltage-controlled device. + Uses only one type of carrier → unipolar device. + Controlled by Gate-Source voltage (VGS). + Has very high input impedance. + Consumes less power since Gate current is almost zero. - 𝐀𝐝𝐯𝐚𝐧𝐭𝐚𝐠𝐞𝐬 + Low power consumption and high efficiency. + Very fast switching speed, ideal for high-frequency circuits. + Better thermal stability compared to BJTs. - 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 + Digital logic circuits and microprocessors. + Integrated circuits (ICs) and CMOS technology. + Power switching, motor drivers, and DC-DC converters. ✍ In short, BJTs are better suited for analog signal amplification where linearity and current gain are important, while FETs dominate digital electronics, low-power designs, and high-speed switching applications. #ElectronicsBasics#CircuitDesign#ElectronicsEngineering#Transistor#BJT#MOSFET#EngineeringStudents

Flicker noise, or 1/f noise, is a type of low-frequency noise that increases in strength as frequency decreases. It can limit the performance of precision electronics like ADCs, RF circuits, and oscillators.

🔌 Understanding Signal Conditioning in Electronics In electronics, raw signals from sensors or circuits often need adjustment before they can be processed. This is where Signal Conditioning comes in. ✨ Key Functions of Signal Conditioning: 1️⃣ Amplification – Boosts weak signals for easier measurement. 2️⃣ Filtering – Removes unwanted noise or frequency components. 3️⃣ Isolation – Protects circuits and prevents ground loops. 4️⃣ Conversion – Transforms signals (e.g., analog → digital). 📍 Example: A temperature sensor may output a small millivolt signal, but before feeding it into a microcontroller’s ADC, it must be amplified and filtered. 👉 Without proper signal conditioning, measurements can be inaccurate, noisy, or even harmful to downstream electronics. ✅ That’s why signal conditioning is the bridge between sensors and processing units in modern electronics.

Day 22 of #100DaysOfElectronics 🔧 Component: Operational Amplifier (IC 741) An Operational Amplifier (Op-Amp) is a high-gain voltage amplifier with differential inputs and a single-ended output. The 741 Op-Amp IC is the most classic and widely used op-amp in analog circuits. 🔹 Symbol: Triangle with inverting (–) and non-inverting (+) inputs, and one output. 🔹 Unit: No direct unit (characterized by Gain, Slew Rate, Input Offset Voltage). 📌 Key Uses: Signal amplification Filters (low-pass, high-pass, band-pass) Comparators Oscillators Analog computing (adder, subtractor, integrator, differentiator) 💡 Fun Fact: The first practical op-amp was invented in 1967 (µA741 by Fairchild). It’s still taught today because of its simplicity and versatility. 🧠 Quick Tip: Use dual power supply (+V and –V) for symmetric operation; in single supply, bias the inputs properly. 🔖 Hashtags: #OpAmp #IC741 #AnalogElectronics #ElectronicsLearning #CircuitDesign #STEMEducation #100DaysOfElectronics #CircuitCrate
