Build your own bypass-capacitor tester
12.08.2016 · Circuits
Most circuits use bypass capacitors and can deliver substandard performance if the capacitors have poor pulse characteristics. Few if any articles cover how to test bypass capacitors for pulse characteristics. The circuit tests these characteristics. It charges the capacitor under test through 100 kΩ for approximately 1 msec and then discharges it through 10 Ω for approximately 40 nsec...

Improve FET-based gain control
12.06.2016 · Circuits
One problem with standard FET gain-control circuits is increased noise when you use the FET as a part of a resistive attenuator in series with an op amp. This configuration attenuates the signal before amplification; hence, it requires much higher gain bandwidth and better noise performance from the op amp. When you substitute the FET for the gain-setting resistor in a noninverting op-amp circuit, distortion limits the circuit configuration to applications in which the input voltage is less than a few hundred millivolts...
TI introduces the industry's first precision nanopower operational amplifiers
