|A fth-order, 4MHz elliptic low-pass Gm-C lter is described, which is tuned by singleintegrator based on-chip tuning circuit. MOS transistors in linear region are used for voltage-to-current conversion in OTA for low voltage operation. The experimental results of the prototype implemented in a 0:8 m CMOS process are given.

In this issue of Neuron, Serbe et al. (2016) use cell-type-specific genetic tools to record and manipulate all major inputs to directionally selective neurons in Drosophila. Their results localize the site of motion computation and reveal unexpected complexity of temporal tuning in the underlying neural circuit.

This paper presents a 0.13μm CMOS 1.7GHz VCO with frequency divider, suitable for ultra-low-power hearing-aid applications. The circuit has a 16% tuning range, a minimum power consumption of 320μW from a 0.8V power supply, power-supply and temperature compensation, an excellent 188dBc/Hz gure-of-merit without the need of off-chip components, and an area of 0.2mm.

This paper presents a very low-power and fully programmable CMOS digital active pixel sensor for uncooled IR fast imaging. The proposed circuit topology includes selfbiasing, built-in input capacitance compensation, predictive A/D conversion and a truly digital I/O interface, all at pixel level. Furthermore, full FPN cancellation is also supplied by the external digital tuning of both offset an...

The shape of the beam profile of a discharge excited XeCl excimer laser using a spiker-sustainer electrical circuit has been varied from a ‘bell’-, through a ‘top-hat’-, to a ‘camel-back’-profile by varying the delay between the spiker pulse and the maincurrent with the circuit operating in the charge-mode. Fine-tuning of the beam profile can be done by varying the charging voltage of the main ...

An intelligent conductivity meter based on MSP430F149 microcontroller was proposed in this paper. The intelligent conductive meter was composed by MSP430F149 microcontroller and its peripheral circuits, bipolar pulse excitation circuit and waveform transform circuit. The MSP430F149 was chosen to control the generation of bipolar pulse excitation signal and take temperature compensation. It adop...

A realization scheme of an electronically tunable multi-terminal floating nullor (ET-MTFN) is described in this paper. The proposed circuit mainly employs a transconductance amplifier, an improved translinear cell, two complementary current mirrors with variable current gain and improved Wilson current mirrors, which provide an electronic tuning of the current gain. The validity of the performa...

Log-domain ®lters are an important class of current-mode circuits having large-signal linearity and increased tuning range over voltage-mode ®lter circuits of similar complexity. In this paper we describe synthesis of a single-ended, ®rst-order ®lter circuit from static and dynamic translinear circuit principles, and show how higher-order ®lters can be easily constructed from the ®rst-order bui...
