  Digitally Programmable, Time-Continuous Active Filter
  PDF, 32 Kb, Archivo publicado: sept 27, 2000
  Programmable active filters have increased in popularity over the past decade. With the advent of switched capacitor topologies, filter parameters such as the natural frequency and filter Q can be changed simply by varying the clock frequency. But switched capacitor filters are sampled data systems and are subject to anomalies such as clock feedthrough noise and aliasing errors.

  Fast Settling Low-Pass Filter
  PDF, 101 Kb, Archivo publicado: sept 27, 2000
  Noise reduction by filtering is the most commonly used method for improving signal-to-noise ratio. The increase in settling time, however, can be a serious disadvantage in some applications such as high-speed data acquisition systems. The nonlinear filter described here is a simple way to get a four-to-one improvement in settling time as compared to a conventional filter.

  Improved Device Noise Performance For the 3650 Isolation Amplifier
  PDF, 28 Kb, Archivo publicado: sept 27, 2000
  The 3650 is an optically coupled, differential input, isolation amplifier having programmable gain. Noise for the 3650 is specified to 4u Vrms (typ) on the input stage of the isolation barrier and 65u Vrms (typ) on the output stage. The gain of the 3650 is controlled using exernal resistors on the input stage. In low gains, the noise performance of the 3650 is dominated by the output stage noise f

  Composite Op Amp Gives You The Best of Both Worlds
  PDF, 32 Kb, Archivo publicado: sept 27, 2000
  Classical op amps such as the OPA627 have excellent performance in applications where the required gain bandwidth is low compared to the gain-bandwidth product of the op amp. However, increasing closed-loop gain decreases the error-reducing loop gain. Furthermore, starting at relatively low frequencies, the loop gain rolls-off at 20dB/decade of signal frequency increase. In combination these effec

  Comparison of Noise Performance of FET Transimpedence Amp/Switched Integrator
  PDF, 66 Kb, Archivo publicado: sept 27, 2000
  Low-input current FET operational amplifiers are universlly used to monitor photodetector, or more commonly photodiode currents. These photodetectors bridge the gap between a physical event, light, and electronics. There are a variey of amplifier configurations to select from and the choice is based on noise, bandwidth, offset, and linearity. A considerable amount has been written on the performan

  Compensate Transimpedance Amplifiers Intuitively (Rev. A)
  PDF, 69 Kb, Revisión: A, Archivo publicado: marzo 30, 2005
  Transimpedance amplifiers are used to convert low-level photodiode currents to usable voltage signals. All too often, the amplifiers have to be empirically compensated to operate properly. The problem can be easily understood if one looks at all the elements involved.

  Noise Analysis for High Speed Op Amps (Rev. A)
  PDF, 256 Kb, Revisión: A, Archivo publicado: enero 17, 2005
  As system bandwidths have increased an accurate estimate of the noise contribution for each element in the signal channel has become increasingly important. Many designers are not however particularly comfortable with the calculations required to predict the total noise for an op amp or in the conversions between the different descriptions of noise. Considerable inconsistency between manufactu
