✦ Synopsis

In this paper, a simple method for the determination of noise coefficients P, R, and C by standard two-port noise parameters, F min , R N and ⌫ opt is presented. The relation between equivalent noise resistance R N and equivalent noise conductance g n has been derived, which greatly simplifies the extraction procedure. This method has been applied to the extraction of K g /K c /K r and P/R/C from 0.15 m InGaAs PHEMT's with three different sizes at two different biases. Excellent agreement between measured and calculated noise parameters has been found. The tendency of the extracted values with respect to device size and bias is also discussed.

The recent paper by Sandvik et al. proposes a method for determining the size of internal pilot studies in the case of two groups and continuous outcome variables. Their method could be slightly improved by taking into consideration follow-up time and accrual rate. The basic idea of their method is
