Top-Down mixed-signal design workflow: from specifications to implementation
PLLs are the key elements in mixed-signal designs. We will see how to adopt a top-down design approach to design the loop filter of a PLL starting from the noise and spectral purity specifications. We will see how to progress from an ideal model towards the simulation of the PLL including analog and digital components and optimize the response of the loop filter.
從上向下的混合訊號設計流程: 從規格到實現 PLL (鎖相迴路設計) 是混合訊號設計中的關鍵要素，我們將採用由上向下的設計方法，從雜訊和頻譜純淨度( spectral purity)規格去設計一個PLL迴路濾波器( loop filter)。我們將可看到從一個理想的模型、PLL模擬(包含類比和數位元件)到迴路濾波器響應的優化等過程的進展。Top-Down mixed-signal design workflow: from specifications to implementation PLLs are the key elements in mixed-signal designs.
