A novel differential-input single-output Operational Transconductance Amplifier (OTA) is presented in this paper. The topology proposed consists of an input stage based on a folded cascoded amplifier, and an output stage based on a current source amplifier and a bulk-driven current mirror. The simulations show that the amplifier has a 1.94μW power(More)
This paper presents a multi-channel sinusoidal generator based in triangle-to-sine (TSC) converters. The proposed signal generator is used as stimulator of electro kinetic micro fluidic platforms for particle manipulation. The device is capable to deliver sixteen independent sinusoidal signals with control of amplitude and frequency. The multi-generator(More)
The G parity-violation experiment at Jefferson Lab (Newport News, VA) is designed to determine the contribution of strange/anti-strange quark pairs to the intrinsic properties of the proton. In the forward-angle part of the experiment, the asymmetry in the cross section was measured for ~ep elastic scattering by counting the recoil protons corresponding to(More)
In this paper, a novel readout method to enhance the readout dynamic range of pixel based on single photon avalanche photodiode (SPAD), is presented. This method overcomes the limitation of existing methods by using a double readout technique based on both time and amplitude measurements without decreasing the fill factor. Another advantage of the proposed(More)
Monte Carlo simulations of a novel concept PET detector for small animal imaging are presented. The scintillation medium of the detector is liquid xenon whose characteristics in terms of detection rival with the common scintillator crystals. Moreover, the axial geometry of the detector enables depth of interaction measurement. A detector module has been(More)
