本論文提出了二個同步錯誤偵測及一個錯誤診斷架構，主要應用於交換電流式電路。我們發展了二個應用於交換電流式積分器與微分器的測試策略。第一個測試策略是根據線性定係數非時變差分方程式的線性特性。第二個測試策略則是根據其線性及反函數的特性。錯誤診斷乃是根據分隔所欲測試之待測電路及其他待測電路以達到錯誤診斷的效果。我們的測試方式有以下的特點 (1) 同步測試 (2) 與待測電路等速 (3) 不需要測試向量產生器 (4) 少量的輸出腳位。
我們使用MATLAB軟體來驗證我們的測試方法並驗證其正確性。並且以HSPICE模擬了一個Regulated 記憶模組及Cascode Bilinear積分器

In this thesis two concurrent error detection methodologies and a fault diagnosis method for Switched-Current circuits are presented. The first error detection methodology is based on the linearity of linear constant coefficient time-invariant difference equations. The second error detection methodology is based on the linearity and the inverse system properties. The fault diagnosis method is based on the isolation between circuit under test and the other circuits. Our test methods have the following characteristics : (1) concurrent testing, (2) at speed testing, (3) no test pattern generator needed, (4) little pin count.
Several MATLAB simulations of our test methods are presented to validate our test methods. A regulated memry cell and a single-end cascode bilinear integratr are also simulated by HSPICE with TSMC 0.6um digital process.
