How to Select a Current Sense Amplifier for Power Monitoring: An Engineering Selection & Error Budget Guide25 August 2026
This guide offers a structured approach to current sense amplifier selection for power monitoring, covering topology choices, key datasheet specs, error budget calculations, and shunt resistor design. It compares analog and digital monitor architectures and highlights common pitfalls, providing practical decision aids and design rules for engineers.
sar-adc-reference-driver-selection-managing-dynamic-kickback-noise-loop-stability17 September 2026
Precision SAR ADCs present high-speed dynamic switched-capacitor loads that demand instantaneous transient currents during bit trials. This guide details how to size local decoupling capacitors accounting for MLCC DC bias derating, stabilize reference buffers using dual-loop in-loop compensation, and minimize multiplicative noise degradation. It also provides layout directives and dynamic bench verification protocols across sampling rate sweeps and burst modes.
ADC Selection Guide: Architectures, Resolution, Sample Rate, and Digital Interfaces18 August 2026
This comprehensive engineering guide outlines how to select the right analog-to-digital converter for mixed-signal systems. It details key architectural trade-offs between SAR, Delta-Sigma, and Pipelined ADCs, provides mathematical models for front-end charge kickback and clock jitter limits, and compares digital interfaces like SPI, LVDS, and JESD204C alongside PCB layout best practices.
Voltage Supervisor Selection: Reset Threshold, Hysteresis, and Release Delay Design Guide21 September 2026
This engineering guide explains how to properly select voltage supervisors to protect microcontrollers from undervoltage failures. It covers calculating worst-case threshold tolerance budgets, sizing hysteresis to prevent reset chattering, and timing release delays for oscillator and PLL stabilization. It also examines push-pull versus open-drain output stages, mitigating sub-1V floating hazards, internal BOR trade-offs, and benchtop transient testing.
What Is an In-Memory Computing Chip? Architecture, Silicon Technologies, and Real-World Hardware27 August 2026
This guide explains how in-memory computing chips reduce AI's memory wall by performing compute inside memory arrays, covering analog and digital execution, SRAM/ReRAM/PCM/DRAM substrates, commercial examples, trade-offs, and a decision framework. It clarifies CIM vs. PIM vs. PNM and highlights engineering limitations like ADC overhead, precision, and software challenges.
eFuse Capacitive Load Startup: Calculate Inrush Current and Prevent Hiccup Trips14 September 2026
An eFuse that repeatedly restarts while charging a capacitor bank needs three checks: how much current reaches the capacitor, how long the pass transistor can sustain the resulting dissipation, and which protection function actually ends the attempt. Reducing the programmed slew rate often helps, but the result also depends on the active load, supply behavior, and the device's startup state machine.
MCU Crystal Selection & Startup Verification: Load Capacitance, ESR, and Oscillation Margin Guide29 September 2026
Prevent MCU clock failures and cold-boot issues by mastering Pierce oscillator circuit design. This comprehensive guide covers exact load capacitance calculations accounting for PCB parasitics, transconductance matching against crystal ESR, drive level protection, and benchtop negative resistance testing. Implement robust production qualification across temperature extremes to ensure rock-solid clock synchronization across hardware revisions.
MSL and Floor Life: A Receiving-to-Reflow Checklist for ICs22 September 2026
This operational guide provides a 5-phase receiving-to-reflow checklist to prevent moisture-induced IC defects and popcorn failures during lead-free reflow. Governed by IPC/JEDEC J-STD-020 and J-STD-033 standards, it details packaging inspection, HIC interpretation, floor-life tracking, ultra-low humidity dry cabinet rules, and carrier-specific baking protocols. It includes a ready-to-use shop-floor traveler log and troubleshooting guidelines for common manufacturing excursions.
Designing Low-Power Optocoupler Circuits: Worst-Case CTR Calculation Across Temperature and Aging24 September 2026
Operating optocouplers at sub-milliamp forward currents extends LED lifespan but causes non-linear CTR collapse. This engineering guide details a multiplicative worst-case CTR derating framework across temperature and Arrhenius aging, covers saturated pull-up resistor sizing, highlights dynamic speed trade-offs, and outlines bench validation protocols using synthetic current starvation to prevent field dropouts.
