The large customer breadth of the Specialty Foundry is driving process technology and design enablement innovation that is hard to replicate within an integrated device manufacturer (IDM) which serves a more focused customer base. In this paper we will review Specialty Foundry technology in the areas of RF, high-performance analog, and power. We will also review novel design enablement tools available...
An adaptive-threshold-voltage differential pair and a low-voltage source follower using independent-double-gate-(IDG-) FinFETs are proposed for a low-voltage operational amplifier (op amp). These circuits were implemented by our FinFET technology that enables co-integration of connected-DG- (CDG-) and IDG-FinFETs. The proposed components enable a two-stage op amp to accept the input below the nominal...
The loop finder (LF) analysis is a newly developed method for automatic loop identification and full chip stability analysis. It allows designers to find local and potentially problematic return loops in their analog circuits. Node impedance transfer functions in pole-residue format are utilized to generate second-order continuous-time systems that approximate the loops. This method was implemented...
This paper proposes an efficient method to predict the lifetime yield of analog circuits considering the joint effects of manufacturing process variations and parameter lifetime degradations. The method uses the idea of worst-case distance, which is an indicator of circuit robustness concerning process variations. The worst-case distance in circuit lifetime is predicted based on a new, quadratic prediction...
