Measuring the linear operating region of instrumentation amplifiers
by Peter Semig and Collin Wells, Texas Instruments There are numerous publications from the past two years that discuss the theoretical linear operating region of instrumentation amplifiers. The publications cover the three primary topologies of instrumentation amplifiers: three-op-amp,[1] twoop-amp,[2] and two-op-amp with gain stage,[3] which are shown in Figure 1. Each publication derives the node […]
Active frequency multipliers double 4 to 23-GHz inputs for radar, comm apps
Pasternack, a leading provider of RF, microwave, and millimeter wave products, has released a new series of active frequency multipliers that simplify system designs by offering high output power levels. Pasternack’s active frequency multipliers are important building block components used in local oscillator (LO) chains for radar, communication receivers and frequency sources to extend frequencies and achieve […]
Should I use an op amp as a comparator?
Perhaps you have a quad pack of op amps, are using only three, and need a single comparator. It might be tempting to use the remaining op amp as a comparator, after all, both have high gain, low offset, and high common-mode rejection. But it’s easier said than done, because a comparator and an op […]
Precision nanopower op amps excel at battery, sensor apps
Texas Instruments today introduced the industry’s first precision nanopower operational amplifiers (op amps). The LPV811 and LPV812 consume quiescent current as low as 320 nA and are part of a family of four new ultra-low-power op amps. With up to 60 percent lower power consumption than competitive precision op amps and offset voltage as low […]
RF MEMS switch matches reliability with excellent RF performance
Analog Devices, Inc. today introduced a breakthrough in switch technology that provides a long-sought replacement for electromechanical relay designs first adopted by the electronics industry more than 100 years ago. ADI’s new RF-MEMS switch technology is enabling faster, smaller, lower power, more reliable instrumentation equipment by resolving multiple performance limitations commonly attributed to relays, whose […]
