Under the Internet of Things initiative, networks are designed to incorporate both sensing as well as switching/control action. The need for control action may arise in different physical domains. Bond graphs are a useful tool which provides modeling of multiple processes that simultaneously take place in different physical domains. The current work discusses the need to develop mathematical models...
In this paper we proposed a new approach to actuate and readout of resonating piezoelectric sensors to realize concept of self-sensing. In the circuit three transistors are used to differentiate between actuation and readout modes. We evaluated a given piezoelectric resonating sensor and the proposed circuit analytically and with simulations. We also evaluated the applicability of our circuit for...
Polymorphic gates can be considered as a new reconfigurable technology capable of integrating logic functions with sensing in a single compact structure. Polymorphic gates whose logic function can be controlled by the level of the power supply voltage (Vdd) represent a special class of polymorphic gates. A new polymorphic NAND/NOR gate controlled by Vdd is presented. This gate was fabricated and utilized...
With technology scaling, vulnerability to soft errors in random logic is increasing. There is a need for on-line error detection and protection for logic gates even at sea level. The error checker is the key element for an on-line detection mechanism. We compare three different checkers for error detection from the point of view of area, power and false error detection rates. We find that the double...
This paper introduces a novel current sense amplifier (CSA) in sub-32nm fully depleted (FD) double-gate (DG) silicon-on-insulator (SOI) technology with planar independent self-aligned gates. A new architecture is proposed which takes advantage of the back gate in order to improve circuit properties. Compared to the reference circuit, the new architecture proves to be faster (21% sensing delay decrease),...
The field of electronic noses and gas sensing has been developing rapidly since the introduction of the silicon based sensors. There are numerous systems that can detect and indicate the level of a specific gas. We introduce here a system that is low power, small and cheap enough to be used in mobile robotic platforms while still being accurate and reliable enough for confident use. The design is...
In deep submicron era, to prevent larger amount of SRAM from more frequently encountered overheating problems and react accordingly for each possible hotspots, multiple ideal run-time temperature sensors must be closely located and response rapidly to secure system reliability while maintaining core frequency. This paper presented a method to extract run-time temperature information from multiple...
A transistor logic memory module based on the Royer oscillator type magnetic multivibrator is described, in which six coils tightly wound around a HTcSC thin disk core are connected to two switching transistors. Oscillation of the module is initiated by applying a pulse current to a coil, and the phase of the oscillation is controlled by the polarity of the trigger pulse. That is, this module is a...
