Abstract :
We present the calculation of noise expressions of low voltage amplifiers by applying symbolic nodal analysis and using nullors. The nullor equivalents of the MOSFETs include only the dominant parasitic elements in order to generate a simplified symbolic noise expression, which provides a good insight to improve the design of low voltage amplifiers. The generated symbolic noise expressions are compared with HSPICE simulations, so that one can appreciate the good agreement with our proposed symbolic noise analysis approach.
