We have developed a foveated imager chip with high resolution photo-cells (referred to as static pixels) in the center that are surrounded by more space consuming adaptive change detection pixels (referred to as dynamic pixels). Inspired by the neurons of biological nervous systems, they emit short voltage pulses, the static pixels with a frequency(More)
In this paper we present a 2 input analog Current-Starved Pseudo-Floating Gate (CSPFG) inverter with capacitive feedback. The analog CSPFG inverter suppresses low frequencies due to the active, local feedback. This inverter can be used in designing filters where a narrow band pass or reject is the main goal. Typical applications are detection of high(More)
In this paper we propose a simple and compact way to realize a bi-directional interface to drive resonant sensors. The bi-directional interface can be set to both activate the resonating sensor (activation mode) and to read its response (read-out mode). During the normal operation of the system these two modes are activated alternatively, depend on the(More)
In this paper we present Auto-Zeroing Current-Starved Floating-Gate Amplifier(AZCSA). In addition to gain, the amplifier allows frequency band adjustment, suited for designing time-continuous analog filters. The Auto-Zeroing Current-Starved Floating-Gate Amplifier(AZCSA) is based on two previously presented floating-gate amplifiers. The AZCSA uses the(More)
In this paper we propose a new front-end for resonating sensors which is based on a logic inverter working as amplifier. The front-end is compact and auto-zeroing which makes it a good candidate for integration and for low power applications. It has been simulated in AMS-350nm CMOS Technology and a prototype has been fabricated using discrete components on(More)
