Petiroc is a 16-channel front-end ASIC designed to readout silicon photomultipliers (SiPMs) for particle time-of-flight measurement applications. Petiroc combines a very fast and low-jitter trigger with an accurate charge measurement. The concept of the ASIC is to combine two measurement lines that won't interfere one with another to measure both first incident photon timing measurement and whole...
The revolution of MIMO radar system has the potential to be applied in many areas of applications such as in agriculture sector. It is inspired from MIMO system in telecommunications and uses multiple antennas to observe the different aspect of targets, hence produce high resolution radar image.
This paper presents application of the SigmaDelta modulation technique to the on-chip dynamic test for A/D converters. The wanted stimulus such as a single- or two-tone signal is encoded into one-bit SigmaDelta sequence, which after simple low-pass filtering is applied to the circuit under test with low noise and without distortion. In this way a large dynamic range is achieved making the performance...
This paper investigates the feasibility of pulse width modulation technique (PWM) for dynamic test of ADCs used for high speed applications. The requirements and limitations of digital PWM signal to noise ratio (SNR) are discussed in terms of pulse-width resolution corresponding to the choice of the carrier- and clock frequency of a pulse-width generator. The PWM SNR response is measured by FFT using...
