Design of a programmable frequency oscillator design using field programmable, analog, CMOS current conveyor has been presented; further, a design methodology to introduce on-chip /field programmability into the second generation current controlled current conveyor circuit (CCCII) is explained. To make the CCCII CMOS design programmable, a floating-gate transistor synapse is introduced to repla...

Integrate-and-fire (IAF) and leaky integrate-and-fire (LIF) models are the popular for spiking neurons neuron networks (SNN). They lack dynamic properties of ordinary differential equations (ODEs) model but simpler. More than half all implementations were digital circuits. The majority them IAF LIF models. resonate-and-fire (RAF) proposed by Izhikevich has both simplicity properties. However, R...

■ User Adjustable Slope Compensation The LT1680 is a high power, current mode switching power supply controller optimized for boost topologies. The IC drives an N-channel MOSFET switch for DC/DC converter applications up to 60V input. A high current gate drive output handles up to 10,000pF gate capacitance, enabling the construction of high power DC/DC converters. Current sense common mode rang...

An effective design procedure has been introduced for implementing the fractional order integrator structures with a modified low pass filters (LPFs) and its functionality is verified by realizing fractional-order chaotic system. In these applications, state variables of Sprott’s Jerk system are emulated first LPFs. Since discrete device based designs have hard adjustment features circuit compl...

In this paper we present a novel RAM-based field programmable mixedsignal integrated device consisting of a Field Programmable Gate Array (FPGA), a set of programmable and interconnectable analog cells, and a microprocessor core. This processor can run general purpose user programs, handle the dynamic reconfiguration of the programmable blocks and probe in real time internal digital and analog ...

A digitally controlled balanced output transconductor (DCBOTA) is proposed and analyzed. The proposed DCBOTA is based on the BOTA given in Ref. 1 and MOS switches. The DCBOTA transconductance is tunable in a range of 2n−1 times using n bits control word. The proposed DCBOTA is simulated using CMOS 0.35μm technology and the results have shown the feasibility of the proposed DCBOTA. The simulatio...
