A CAD Methodology for Switched Current Analog IP Cores

Abstract − As system chips begin to absorb analog functionality there is increasing interest into what makes a good analog IP core. Research suggests that a solution could be the transistoronly switched current analog circuit technique, perfectly suited to modern digital processes. However, many designers are unfamiliar with this technology, favouring more conventional approaches not hindered by a lack of supporting CAD tools. To address this problem we have developed a CAD methodology, which allows rapid generation of switched current analog IP cores. This recently developed system has already shown good success with filter design and is being expanded to include other major analog functions. I
