- Clamping Circuit Lowers Distortion, Improves Overdrive Recovery TimeSome amplifier applications require clamping or limiting due to large, sporadic signals appearing at the amplifier input. Clamping these errant signals protects the amplifier and other sensitive downstream circuitry. It...25-04-2022
- A Practical Guide to High-Speed Printed-Circuit-Board LayoutDespite its critical nature in high-speed circuitry, printed-circuit-board (PCB) layout is often one of the last steps in the design process. There are many aspects to high-speed PCB layout; volumes have been written on...

- Differential driver doubles as versatile RF-switch driverDesigned as a high-speed driver for 12-bit ADCs, the AD8137 controls SPDT GaAs (gallium-arsenide) FET-MMIC (microwave-monolithic-IC) and PIN-diode RF switches and thus provides a low-cost and versatile alternative to...04-07-2018
- InexpensIve High-speed Amplifiers Can Create Flexible Clock BuffersIn consumer electronics applications, which tend to be lower in frequency and less demanding than typical clock-buffering applications, inexpensive high-speed op amps (~100-MHz bandwidth) can offer an attractive option...02-04-2018
