Power-efficient, Precise Discriminator for a High Time Resolution, Low-Noise Charge Detection ROIC

Pixel charge detectors are responsible for counting the number of collected electrons and converting it into an electrical signal. The proposed charge detector pixel readout integrated circuit (ROIC), implemented in 40nm TSMC technology, should be able to detect an amount of charge as low as 160aC, with a high time resolution of 2.5ns, using...

Single Electron Readout Circuit: SERCuit

Particle detection circuits are used for a wide range of applications from experimental physics to material testing and medical imaging. State-of-the-art imaging systems demand the detection of small amounts of charge with small time-resolution and limited power consumption, creating an implementation dead-end for the typical readout topology....

High-Speed Readout Circuit for PIN Single Electron Detector in Voltage Mode

This thesis proposes the design of a new type of read-out circuit for a PIN diode used in Scanning Electron Microscope (SEM) applications. The circuit operates in voltage mode (with high input impedance), which offers significant power-saving advantages over the traditionally used current mode (with low input impedance). The final read-out...
