....amplifiers, and a comparator which is responsible for selecting the active amplifier. Furthermore, it has internal laser trimmed thin film resistors which are very accurate and temperature stable. For the low pass responses in the demodulation scheme, a unity gain Sallen Key low pass realization [6] was chosen for simplicity, and the fact that its dc gain is always equal to one, independent of variations in the values of the passive components. This is important since resistor and capacitor values vary with environmental conditions. If the dc filter gain is sensitive to the environment, the ....

Our 0 7803 5643 8 99 10.00 1999 IEEE November 10 13, 1999 San Juan, Puerto Rico text [3] is used as a reference for the description of the circuits found on the IIB and a general discussion of the integrated circuits found on the SDAS. We continually refer to the IIB schematic, find the circuit for that day s lecture, and use the material in the book to learn about the circuit. The ....

....Temperature Controller [2] is a control system for preserving temperature in a predefined range. The names of Telephone Set [18] Power Meter [7] Iterative Equation Solver [21] Differential solver for a missile guider [11] are self explanatory for their functionality. Dual slope A D converter [5] is an analog to digital converter, Rimoldy Diversity Receiver [16] and Massey s Diversity Receiver [16] are modulation schemes used in telecommunication. We also developed two artificial examples for some missing functional aspects, and which are indicated by the generic names Example1 and ....

....with multiple modes of functioning) Events for the control part and control signals for the analog part are produced either inside or outside the analog system. The functionality of all real life examples is expressed in time, although behavior in frequency is also very common for analog systems [5]. The additional examples that we will develop address the issue of functionality in frequency. The behavioral model points to some of the basic language constructs of any synthesis oriented subset. A subset should include language constructs for describing the functional aspects pertaining to ....

....performance characteristics) that go through distinct design steps, in our synthesis environment. At this point, its worthwhile to stress that, in the context of our work, by event driven part we also mean analog sub components having this kind of functionality. The behavior of analog circuits [12] i.e. voltage comparators, zero cross detectors, Schmitt triggers, is a typical event driven one. Although ultimately, an eventdriven behavior can also be expressed in continuous time, we prefer the first style, as it reduces simulation time and simplifies synthesis. The rest of this section ....

....indicate their kind (voltage) and output earph is also augmented with information about its limiting and driving characteristics. Besides, a declarative description style can be complementary to traditional description methods. Typically, the behavior of filters is expressed as transfer functions [12]. Nevertheless, if the transfer function is provided, then also the filter type, and its structure are decided. Instead, we could describe signal properties along the signal path, i.e. frequency ranges, and let the synthesis tool infer an appropriate filter type. Currently, VASS accepts ....

....3 depicts the signal flow graph obtained for the receiver module after compiling the input VHDL AMS behavioral specification. The Architecture Generator maps a VHIF representation, into netlists of circuits at the component level, which is the highest level of abstraction for system level designs [12]. For producing all possible mappings, the branch and bound algorithm relies on VHIF representations for all components in the library [3] The analog library contains topologies for some of the most commonly used analog circuits: operational amplifiers, filters, converters, etc. Besides the VHIF ....

....branching rule contemplates two kinds of transformations, in a signal flow graph. Functional transformations replace a particular block structure with a distinct, but semantically equivalent structure, i.e. for improving bandwidth, an op amp is replaced by a chain of two op amps with lower gains [12], or two non inverting amplifiers are substituted for by two inverting amplifiers [12] etc. Transformations pertaining to circuit interfacing introduce additional circuits, i.e. follower circuits [12] or various input output stages [12] etc. for diminishing loading coupling effects among ....

The unknown system is a discrete analog circuit designed to implement a standard Sallen Key low pass filter shown in Figure 3b [1]. This type of problem is typically solved with adaptive filters but rarely are continuous time aspects considered. The input to the system was a pseudo random bit stream that was filtered to achieve a flat spectrum noise input. The system is set up as shown in Figure 3(a) so that the gamma filter ....
