A large dynamic range integrated front-end for photomultiplier tubes

Photomultiplier Tubes

Light which enters a photomultiplier tube is detected and produces an output signal through the following processes. (1) Light passes through the input window. (2) Light excites the electrons in the photocathode so that photoelectrons are emitted into the vacuum (external photoelectric effect). (3) Photoelectrons are accelerated and focused by the focusing electrode onto the first dynode where ...

Photomultiplier Tubes

including basic and performance. For example, section 4.1 shows spectral response characteristics of typical photocathodes and also gives the definition of photocathode sensitivity and its measurement procedure. Section 4.2 explains dynode types, structures and typical characteristics. Section 4.3 describes various performance characteristics such as time response, operating stability, sensitiv...

A Review of High Dynamic Range Front-End Amplifiers

High dynamic range 60 MHz powerline front-end IC

Presented for the first time, is a novel broadband powerline front-end realised in 0.25 mm SiGe BiCMOS with superior performance. The frequency range of the transmitter (TX) and the direct conversion receiver (RX) exceeds 60 MHz with a very wide dynamic range up to 99.5 dB for the lowest channel bandwidth. The integrated IF filter is tunable from 1 up to 8 MHz. The measured input-referred noise...

SP 22.3: A 12mW Wide Dynamic Range CMOS Front-End for a Portable GPS Receiver

To achieve a wide dynamic range, the noise figure of the LNA and linearity of the mixer are of primary concern. Figure 2 shows the circuit schematic of the LNA. A differential architecture is chosen in anticipation of eventual integration of a complete GPS receiver. Its common mode rejection eases the task of rejecting interference from other on-chip elements, such as a DSP core. This choice re...
