Technical Analysis Articles
NTC Thermistor Replacement: Beta, Tolerance and Self-Heating
Compare NTC temperature-sensor alternates using the resistance curve, beta definition, tolerance and self-heating, with explicit numerical examples.
Comparator Selection: Overdrive, Delay and Output Interface
Evaluate comparator delay at actual overdrive, output loading and logic thresholds; separate pull-up rise time, hysteresis and guaranteed timing limits.
RTD Interface Selection: Two-, Three- and Four-Wire Error Budgets
Choose an RTD interface using lead resistance, three-wire mismatch, four-wire sensing, excitation current and a temperature-error budget tied to the sensor.
Ferrite Bead Selection: DC Bias, Impedance and Filter Resonance
Choose ferrite beads for power rails using impedance under DC bias, resonance, damping and measured filter behavior across the actual load range.
Precision DAC Selection: Settling, Glitch Energy and Output Load
Compare precision DACs using the required error band, analog settling, glitch impulse, reference behavior and loaded output timing, rather than resolution alone.
Clock Buffer Selection: Additive Jitter, Output Skew, and Termination
Select a clock buffer by signal format, additive jitter, phase-noise integration, output skew, loading, termination, power noise, and enable behavior.
Common-Mode Choke Selection: Impedance, Leakage, Current, and Saturation
Select a common-mode choke at the noise frequency while checking leakage inductance, differential loss, rated current, imbalance, saturation, parasitics, and safety.
Current-Shunt Resistor Selection: Kelvin Layout, TCR, and Pulse Energy
Choose a current shunt by balancing full-scale drop, amplifier error, TCR, self-heating, Kelvin connection, pulse loading, and PCB thermal design.
Resettable PPTC Selection: Hold Current, Trip Time, and Temperature Derating
Select a resettable polymer fuse from ambient-derated hold current, fault-current trip curves, maximum interrupt conditions, resistance, reset behavior, and aging.
Thermocouple Interface Design: Build a Cold-Junction Error Budget
Budget thermocouple measurement error across the sensor, cold junction, thermal gradient, amplifier, ADC, reference, filtering, and linearization.
