In PSpice for Analog Communications Engineering we simulate the difficult principles of analog modulation using the superb free simulation software Cadence Orcad PSpice V10.5. While use is made of analog behavioral model parts (ABM), we use actual circuitry in most of the simulation circuits. For example, we use the 4-quadrant multiplier IC AD633 as a modulator and import real speech as the mod...
Electronically tunable RC-active ladder filter transfer fun& tions ore realized by employing the four quadrant analogue multiplier os the basic nonlinear network element. All the frequency dependent branches of a conventional RC-active ladder structure realizations ore simulated by means of impedance scaling networks. The scaling of these impedances allows the cutoff frequency of an elliptic lo...
A pseudodifferential CMOS operational transconductance amplifier (OTA) with wide tuning range and large input voltage swing has been designed for very small ’s (of the order of a few nanoamperes per volt). The OTA is based on a modified four-quadrant multiplier architecture with current division. A common-mode feedback circuit (CMFB) structure has been proposed and designed using floating-gate ...
We present a novel floating-gate ultra lowvoltage (ULV) analog multiplicator with tunable linear range. Rail to rail operation is provided in the symmetric analog “gates” presented which are utilized in the ULV analog multiplier described in this paper.
the thesis has been arranged into five chapters and mainly concerned with the baer-invariant of groups which is the generalization of the schur-multiplier with respect to the variety of groups. chapter one is devoted to collect some notation and background information which are needed in the next chapters. its also contains some important statements which will be generalized in this thesis. cha...
This paper presents a switched current multiplier, dedicated for the use in highly parallel computation arrays or neural networks. It is designed for 3V supply voltage, performing 50k multiplications per second with a power dissipation of 100nW and an accuracy better than 1.5% considering the presence of possible device-mismatch. 2nd Electronic Circuits and Systems Conference ECS’99, 6-8th Sept...
