The Multiple-input Translinear Element: a Versatile Circuit Element
We define the multiple-input translinear element (MITE), a versatile circuit primitive from which we can construct lowvoltage translinear circuits and log-domain filters. A K-input MITE produces an output current that is exponential in a weighted sum of its K input voltages. We briefly discuss six MITE implementations and show experimental data from two of these six that we have fabricated in a...
متن کاملClass-AB Square-Root Domain Filters Based on the Floating
In this paper a new approach for design of class-AB current-mode square-root domain filters based on the electronically simulated translinear loop principle is presented. FG-MOS transistors that operate in strong inverted saturation region are employed for implementation of translinear loop circuit. The filter achieves immunity to body effect, low circuit complexity, large input dynamic ran...
متن کاملLog-Domain Filtering and the Bernoulli Cell
In this paper, the dynamic behavior of a nonlinear circuit element termed a Bernoulli cell is described, which is composed of a suitably biased bipolar junction transistor (BJT) and an emitter connected grounded capacitor. This cell has application in the synthesis of log-domain filters, since it facilitates the development of a low-level design approach in which a frequency-domain transfer fun...
متن کاملMultiple-Input Translinear Element Networks
We describe a new class of translinear circuits that accurately embody product-of-power-law relationships in the current signal domain. We call such circuits multiple-input translinear element (MITE) networks. A MITE is a circuit element, which we defined recently, that produces an output current that is exponential in a weighted sum of its input voltages. We describe intuitively the basic oper...
متن کاملLog-Domain Filters Based on LC Ladder Synthesis
A design method is proposed for the synthesis of linear, high-order, continuous-time filters using a unique translinear integrator circuit. Unlike previous attempts at incorporating translinear circuits into filter design, the proposed theory makes explicit use of the exponential nature of the bipolar transistor. This technique is based on the operational simulation of LC ladders. A 5th-order C...
