  • Abstract
    In this paper, systematic mismatch due to parameter gradients is modeled and analyzed. A new layout strategy with flexible cell placement is proposed. Theoretical analysis shows its property of canceling the mismatch between two devices due to up to nth order gradient effects by using 2n unit cells for each device. Simulation results show that the proposed technique gives better matching characteristics than other existing layout techniques under nonlinear gradients.
