A comparison of substrate noise coupling in heavily doped and lightly doped substrates for mixed-signal circuits

Creator:: Ayers, James S.
Abstract:: An analysis of substrate noise coupling in mixed-signal circuits has been performed in the TSMC 0.25 [mu]m lightly doped and heavily doped CMOS processes. Methods to minimize noise coupling in both the chip design and board design phases are presented along with techniques for accurate circuit simulation of noise coupling....

Computationally efficient substrate noise coupling estimation in lightly doped silicon substrates

Creator:: Srinivasan, Kavitha
Abstract:: A Z-parameter based macromodel for characterizing the substrate noise coupling in a lightly doped substrate at low frequencies has been developed. The model is scalable with contact geometries and separation. The cross-coupling impedance between two contacts is modeled using an improved geometric mean distance formulation. This approach obviates the need...

Noise optimization for low-voltage CMOS audio preamplifier systems

Creator:: Brown, Matthew Eugene
Abstract:: There is a large and growing market for portable consumer audio products with very small size. As the size of these products is reduced, the area occupied by batteries becomes significant and hence limits the number of batteries to one. In order to build such small products, high levels of...

Analysis and modeling of substrate noise coupling for NMOS transistors in heavily doped substrates

Creator:: Hsu, Shu-ching
Abstract:: This thesis examines substrate noise coupling for NMOS transistors in heavily doped substrates. The study begins with the analysis of an NMOS transistor switching noise in a digital inverter at the device level. A resistive substrate network for the NMOS transistor is proposed and verified. Coupling between N+- P+ contacts...

An efficient and accurate method of estimating substrate noise coupling in heavily doped substrates

Creator:: Arunachalam, Sasi Kumar S.
Abstract:: This thesis presents a Z-parameter based model to predict the substratenoise coupling between two contacts in a heavily doped substrate for frequenciesless than 2 GHz. The empirical model is scalable with contact size and spacingsbetween the contacts and model parameters can be readily extracted from simu-lated or measured data. The...

A comparison of substrate noise coupling in lightly and heavily doped CMOS processes for 2.4 GHz LNA's

Creator:: Hazenboom, Duncan S.
Abstract:: Three types of low noise amplifiers operating at 2.4GHz were designed. They are the commonly used single-ended and differential amplifiers as well as a new quasi-differential amplifier. The substrate noise injected into these amplifiers is examined for both heavily and lightly doped CMOS substrates. For the single-ended amplifier the noise...

Feedforward noise cancellation techniques

Creator:: Yang, Bangda
Abstract:: Supply noise is one of the major considerations in almost all analog building blocks. In the past, adequate supply rejection is usually achieved with circuit isolation or excess capacitive coupling. However, this brute force method requires large silicon area and degrades feedback bandwidth. In this study, a method of enhancing...
