Low Voltage Power Efficient Tunable Shaper Circuit With Rail-To-Rail Output Range for the HYDE Detector at FAIR

Energy-Efficient Amplifiers Based on Quasi-Floating Gate Techniques

“…This current follower/amplifier can be implemented by either a current mirror or a common-gate configuration, leading to the current-mirror (symmetric) and folded cascode amplifiers, respectively [22]. An example of class AB current mirror amplifier is presented in [23]. If high gain is required, a cascode current mirror implementation can be used, as shown in Figure 6c, in fully differential version (CMFB circuit not shown) [22].…”

“…At the same time, large dynamic currents can be provided, since signals are capacitively coupled to the high impedance gate node. Due to these advantages, QFG transistors have found widespread use in the design of amplifiers but also in high-performance current mirrors [31][32][33][34][35], mixers [36,37], linearization of active resistors [38,39], DC offset cancellation servo loop circuits [40], bootstrapped switches [5], current conveyors [30,[41][42][43], Voltage Feedback Operational Amplifiers (VFOAs) [44], Current Feedback Operational Amplifiers (CFOAs) [45], buffers [46][47][48][49][50][51], rectifiers [35,52], capacitance multipliers [35], transconductors [30,[53][54][55], digital-based analog circuits [56], DC-DC converters [57], continuous-time filters [58][59][60][61], track and hold circuits [5], data converters [5,62], capacitive sensing interfaces [63], particle detectors [23] and retinal prosthesis [64], to name some representative applications.…”

Analog CMOS Readout Channel for Time and Amplitude Measurements With Radiation Sensitivity Analysis for Gain-Boosting Amplifiers

“…In this expression, α encompasses the noise components corresponding to detector leakage current, detector bias resistance RBIAS, and CSA feedback resistance, RF; ap is the white current noise coefficient, CG represents the gate capacitance of the CSA input transistor, β represents the CSA input transistor thermal noise component, aw is the white voltage noise coefficient, AF is the CSA input transistor 1/f noise coefficient and af represents the 1/f voltage noise coefficient. The coefficients ap, aw, and af, related to the shaper transmittance function H(s) and the CR-(RC) 4 complex filter are, respectively, 0.51, 0.91, and 0.53 [37]. Note that for M1 in strong inversion the β coefficient is proportional to (8kT)/3gm1.…”

“…The design of readout front-end channels finds great interest nowadays in applications where the sensor response to external physical stimulus is given in form of electrical charge, typically a short current pulse. Signal processing from radiation detectors for nuclear or particle physics, or medical imaging applications, are particular fields where FEE are widely used, with a trend towards complete system on chip design solutions [1]- [4].…”
