Analog and Mixed-Signal IC Security via Sizing Camouflaging

We treat the problem of analog integrated circuit (IC) obfuscation toward intellectual property (IP) protection against reverse engineering. Obfuscation is achieved by camouflaging effective geometry layout components via use fake contacts, which originally were proposed for gate in digital ICs. present a library obfuscated components, we give recommendations camouflaging, discuss foreseen attacks and resiliency, propose security metrics assessing hardness The methodology demonstrated on an operational amplifier RF ?? analog-to-digital converter (ADC).
