This circuit uses a low power op Amp and a p-channel FET to form a diode function with a very low 0.05 volt voltage drop...
Circuit forms ideal diode function
Vishay Intertechnology AEC-Q200 qualified, 50 W thick film power resistor offers high reliability for automotive applications
To meet the growing demand for high performance electronic components in next-generation automotive applications, Vishay Intertechnology introduced a new AEC-Q200 qualified, 50 W thick film power resistor in a compact TO-220 package for direct mounting on a heatsink...
A digital frequency detector
I designed the circuit as a part of a data transmission system that has a carrier frequency of 400 kHz using on-off keying (OOK) modulation...
Littelfuse expands magnetic sensor portfolio with high-precision TMR angle sensors
Littelfuse, Inc. announced the launch of two new TMR-based magnetic angle sensors - the LF53466 and LF53464 - designed to deliver high-precision 0–360° angular measurement in harsh environments with minimal thermal drift...
Circuit forms divide by 1.5 counter
Two inexpensive ICs divide a TTL clock signal by 1.5...
Dropping a PRTD into a thermistor slot - impossible?
Up front: some background. The air-temperature sensor attached to my rain gauge became flaky...
Buck regulator and two inductors make dual-polarity converter
A common problem for power-supply designers is to create a compact, dual-polarity step-down converter. If space and cost are not concerns, the obvious solution is a pair of DC/DC converters, one for each output...
Analog frequency doublers
High school trigonometry combined with four-quadrant multipliers can be exploited to yield sinusoidal frequency doublers. Nothing non-linear is involved, which means no possibly strident filtering requirements...
Drive any electronic clock with a high-precision 10-MHz reference
Most electronic clocks, be they analog or digital, use a crystal oscillator based on a 32.768 kHz crystal for their reference. In fact, it is same crystal that’s commonly used as a real-time clock for many microcontroller systems...
Improve PWM controller-induced ripple in voltage regulators
Simple linear and switching voltage regulators with feedback networks of the type shown in Figure are legion. Their output voltages are the reference voltage at the feedback (FB) pin multiplied by...
