A New Circuit Scheme for Wide Dynamic Circuits
In this paper, a new circuit scheme is proposed to reduce the power consumption of dynamic circuits. In the proposed circuit, an NMOS keeper transistor is used to maintain the voltage level in the output node against charge sharing, leakage current and noise sources. Using the proposed keeper scheme, the voltage swing on the dynamic node is lowered to reduce the power consumption of wide fan-in...
متن کاملLow Noise Wide Dynamic Range Image Sensor Readout using Multiple Reads During Integration (MRDI)
Thermal noise sets the fundamental detection limit for silicon photodiode based image sensors. In this paper we present a technique for nondestructively reading PDI image sensors, called multiple read during integration (MRDI), which reduces thermal read noise by using oversampling. This paper discusses the operation of MRDI, presents an illumination estimator, and analyzes the resulting noise ...
متن کاملLow-cost current-to-voltage converter for DC measurements in a wide dynamic range
Abstrac t-A logarithmic current-to-voltage converter for measuring DC currents in a wide dynamic range (from 1 pA to 1 mA) is described here. The converter is based on an operational amplifier circuit with a standard commercially-available LED diode used as a nonlinear feedback. A temperature compensation method requiring only one reference amplifier was used. This significantly reduces the com...
متن کاملLow-Power Low-Noise CTIA Readout Integrated Circuit Design for Thermal Imaging Applications
This paper targets the design of a high dynamic range lowpower, low-noise pixel readout integrated circuit (ROIC) that handles the infrared (IR) detector’s output signal of the uncooled thermal IR camera. Throughout the paper, both the optics and the IR detector modules of the IR camera are modeled using the analogue hardware description language (AHDL) to enable extracting the proper input sig...
متن کاملA low-power readout circuit for nanowire based hydrogen sensor
This paper presents a fully integrated lock-in amplifier intended for nanowire gas sensing. The nanowire will change its conductivity according to the concentration of an absorbing gas. To ensure an accurate nanowire impedance measurement, a lock-in technique is implemented to attenuate the low frequency noise and offset by synchronous demodulation or phase-sensitive detection (PSD). The dualch...
