Design of a Mixed-signal ASIC for the front-end electronics of ionisation chambers


New technical paper titled "An Ultra Low Current Measurement Mixed-Signal ASIC for Radiation Monitoring Using Ionisation Chambers," by researchers at CERN. Abstract "Measurement of total ionizing dose in a radiation field is efficiently carried out by ionisation chambers. The paper details the design of a mixed-signal ASIC for the front-end electronics of ionisation chambers. A single c... » read more

Brute-Force Analysis Not Keeping Up With IC Complexity


Much of the current design and verification flow was built on brute force analysis, a simple and direct approach. But that approach rarely scales, and as designs become larger and the number of interdependencies increases, ensuring the design always operates within spec is becoming a monumental task. Unless design teams want to keep adding increasing amounts of margin, they have to locate th... » read more

Circuit-Device Co-design for High Performance Mixed-Signal Technologies


System-on-Chip designs require low cost integration of analog and digital blocks. Often, the analog requirements are not considered sufficiently early in the device design cycle, resulting in devices that are suboptimal for the analog components. This paper presents an innovative methodology for deriving comprehensive device specifications based upon a set of Figure-ofMerit circuits which accou... » read more

Interpreting UPF For A Mixed-Signal Design Under Test


This paper describes a methodology (as implemented in the Mentor Graphics Questa ADMS mixed-signal simulator) for interpreting the Unified Power Format (UPF) for analog mixed-signal designs coded in Verilog-AMS, VHDL-AMS, or SPICE. No changes to the UPF syntax or file are required. A complete implementation and a demonstration of its use in a sample case are provided as proof of concept. To ... » read more

The New Mixed-Signal Flow


By Ann Steffora Mutschler We are on the cusp of the mixed-signal era. Traditional mixed-signal design environments, in which analog and digital parts are implemented separately, no longer are sufficient. They lead to excess iteration and prolonged design cycle time. Today’s mixed-signal designs require a new approach that enables design teams to be as efficient as possible productivity... » read more

The Double Whammy


By Ann Steffora Mutschler Given that at 40nm and below every [getkc id="81" kc_name="SoC"] has some mixed-signal content, combined with the fact that power awareness is top priority no matter what the target application is, design teams and verification engineers are grappling with tremendous challenges just to get a chip to yield. “For verification engineers and for designers, this is a ... » read more
