1999-12-14 Noise analysis of FET transimpedance amplifiers
The availability of detailed noise spectral density characteristics for the OPA111 amplifier allows an accurate noise error analysis in a variety of different circuit configurations. The fact that the spectral characteristics are guaranteed maximums that allow absolute noise errors to be truly bounded. Other FET amplifiers normally use simpler specifications of rms noise in a given bandwidth (typically 10Hz to 10kHz) and peak-to-peak noise (typically specified in the band 0.1Hz to 10Hz). These specifications do not contain enough information to allow accurate analysis of noise behavior in any but the simplest of circuit configurations. This application note discusses in detail how the OPA111 is utilized to perform noise error analysis in different circuit configurations.

2007-05-04 A simple glass breakage detector using the MSP430
This application report describes a simple glass breakage detector using the MSP430F2274 ultralow-power MCU. The algorithm is based on the spectral analysis of a typical glass breakage signal. The input signal spectrum, limited to a frequency of 20kHz, is processed for a valid glass breakage. Various signal characteristics such as peak content, number of zero crossings, and frequency composition are analyzed. Real-time signal processing is achieved by implementing and using a low-order bireciprocal lattice wave digital filter (LWDF). A glass breakage alert is indicated by an onboard buzzer and an LED. The entire setup is designed to operate at low power, allowing long battery life.
