Synthesis Of Translinear Analog Signal Processing Systems, Eric Mcdonald, Bradley Minch
Synthesis Of Translinear Analog Signal Processing Systems, Eric Mcdonald, Bradley Minch
Bradley Minch
In this paper, we describe a structured methodology for synthesizing translinear analog signal-processing systems from high-level descriptions in the time domain. The circuits are implemented from elements called multiple-input translinear elements (MITEs). We illustrate the synthesis methodology with the simple example ofan RMS-DC converter.

Synthesis Of Static And Dynamic Multiple-Input Translinear Element Networks, Bradley Minch
Bradley Minch
In this paper, we discuss the process of synthesizing static and dynamic multiple-input translinear element (MITE) networks systematically from high-level descriptions given in the time domain, in terms of static polynomial constraints and algebraic differential equations. We provide several examples, illustrating the process for both static and dynamic system constraints. Although our examples will all involve MITE networks, the early steps of the synthesis process are equally applicable to the synthesis of static and dynamic translinear-loop circuits.

In this paper a second order log-domain bandpass filter using multiple input translinear elements (MITEs) operating at a 3V supply. We enhance the capabilities of the filter by utilizing programmable MITE structures as well as programmable current sources, which are covered in this paper. The synthesized bandpass filter is implemented and fabricated using these programmable translinear devices (MITEs). Experimental results are shown from circuit fabricated on a 0.5μm nwell CMOS process available through MOSIS.

Low Voltage And Performance Tunable Cmos Circuit Design Using Independently Driven Double Gate Mosfets, Arvind Kumar, Bradley Minch, Sandip Tiwari

Independently driven double-gate MOSFETs (DGFETs) facilitate design of analog circuits under digital logic constraints and provide in-circuit parameter adaptability through threshold voltage control. Threshold voltagetuning is achieved by biasing one of the two gates where as strong coupling of surface potentials at the two interfaces provides a low resistance feedback path. The geometry also allows a back-floating gate NVRAM structure with superior scalability and floating gate related analog applications without any read disturbance. This paper gives examples across breadth of circuits where this tunability is exploited.
