This paper presents the design flow from system-level specifications to transistor-level design for three different fully-differential amplifiers composing the first and the second integrator of a second-order hybrid multi-bit ΔΣ modulator. The circuit-lev ...
This paper presents a hybrid continuous-discrete-time Delta-Sigma modulator for portable communication systems following a low-power strategy. The proposed design methodology is extendable to different specifications. A multi-bit technique has been introdu ...
Standard analog design procedure is usually based on a large number of simulations, strongly depends on the type of analog circuit that has to be implemented and requires a lot of manipulation at the transistor level. Simulators offer accurate modeling and ...
This paper presents a new Procedural Analog Design tool called PAD. It is a chart-based design environment dedicated to the design of analog circuits aiming to optimise design and quality by finding good tradeoffs. This interactive tool allows step-by-step ...
