A high performance automatic gain control (AGC) circuit of analog type is presented in this paper. The proposed AGC incorporates a modified sample and hold peak-detector. Circuit operations of this new peak-detector are demonstrated superior to the conventional one, by both keeping and tracking the peak of the input signal at the same time. Furthermore, the design complexity of the proposed AGC...

On chip testing is an attractive solution for testing of analog integrated circuits. In this paper a low power , built in CMOS Ripple Detector is presented for the purpose of detecting the ripples in the supply rails and specifies its application for On chip testing. The detector works on the principle of RMS detection. The circuit outputs a DC signal that is proportional to the peak to peak am...

found in the response of the electron-capture detector for fatty acids of niicrosomal lipids from CC1,-treated rats (the latter peak is clearly a group of unresolved peaks). Since serum very-low-density lipoproteins derive directly from the hepatic cell and since the phospholipid fraction of such lipoproteins is believed to derive from the phospholipids of the endoplasmic reticulum, we investig...

Room-temperature detector, manufactured by the company ‘‘SPINOR’’ (Tomsk Russia) was tested for the investigations of the coherent synchrotron radiation characteristics at the bent electron beam of FLASH (Hamburg) in the wavelength region 0.5–3mm. Detector is based on a low-threshold diode and a broadband antenna with a built-in preamplifier. The detector characteristics allowed us to measure a...

A compact and accurate readout system has been developed for high-rate spectroscopy with multi-element detectors. The fully self-triggered system multiplexes the signals from 32 detectors into a novel peak detector, which also serves as a derandomizer. The captured pulse heights are stored as analog samples before being presented to the ADC along with the corresponding channel addresses. The pe...

An onset detector is described based on the most successful onset detector for non-pitched percussive audio events from an earlier comparative study (Collins, 2005a). The detection function is an adaptation of the log intensity difference change discrimination originally introduced by Anssi Klapuri (Klapuri, 1999). A novel peak picking method is used based on scoring the most salient peaks with...

The introduction of the diode array detector helped overcome this problem by providing access to quantitative as well as qualitative spectral information for a wide wavelength range. Agilent Technologie introduced the first diode array detector for liquid chromatography in 1982. Since that time significant improvements in the design of both the hardware and software have been made, Enhanced Dio...
