“…Then, in order to improve the Signal-to-Noise Ratio (SNR), the CPA output voltage is filtered by a circuit called pulse shaper (PS). As in [14], a first order semi-Gaussian PS (RC-CR bandpass filter) is used as PS for its high-speed response and its active bandpass filtering characteristics. These two blocks are widely used for such detectors [1]- [3], [14], [18].…”

“…This issue is of up most importance here as each channel includes a peak-detector and a SAR ADC. Therefore, to address this extrinsic noise, a differential input stage (Fig.2) is used instead of the usual single-ended architecture [14], [15]. Nevertheless, the equivalent input noise power spectrum is doubled compared to a single transistor amplification stage (if each transistor is biased by the same current), which corresponds to a noise increase by a factor of √ 2.…”

“…Here, the PS is limited to a first order band pass filter, in order to reduce the power consumption and circuit complexity. Based on [14], the ENC of the system including the Si sensor, the CPA and the PS ENC tot can be expressed as:…”

A low power analog front-end circuit for silicon (Si) detectors has been fabricated in 0.35 µm CMOS technology. It has been designed to read out signals from large-capacitance Si detectors for incident electron energy ranging from 50 keV to 725 keV. In order to quantify electron energy, the front-end integrates a charge preamplifier, a pulse shaper, a peak detector and an event-driven analog-to-digital converter (ADC). The complete front end including the ADC dissipates 2.5 mW for a maximum electron detecting rate of 650 kHz. The charge-to-voltage gain is approximately 60 mV/fC for a charge range of 0.6 fF to 32 fF. The measured equivalent noise charge (ENC) is 3119 e − for a 40 pF detector parasitic capacitance. Index TermsSi Detector, Charge preamplifier, electron energy measurement.

Large biomolecules and bioparticles play a vital role in biology, chemistry, biomedical science and physics. Mass is a critical parameter for the characterization of large biomolecules and bioparticles. To achieve mass analysis, choosing a suitable ion source is the first step and the instruments for detecting ions, mass analyzers and detectors should also be considered. Abundant mass spectrometric techniques have been proposed to determine the masses of large biomolecules and bioparticles and these techniques can be divided into two categories. The first category measures the mass (or size) of intact particles, including single particle quadrupole ion trap mass spectrometry, cell mass spectrometry, charge detection mass spectrometry and differential mobility mass analysis; the second category aims to measure the mass and tandem mass of biomolecular ions, including quadrupole ion trap mass spectrometry, time-of-flight mass spectrometry, quadrupole orthogonal time-of-flight mass spectrometry and orbitrap mass spectrometry. Moreover, algorithms for the mass and stoichiometry assignment of electrospray mass spectra are developed to obtain accurate structure information and subunit combinations.
