High Frequency CMOS Transconductors
S. Dupuie, Mohammed Ismail · Institution of Engineering and Technology eBooks · 1993
The primary goal of this chapter is to highlight the important aspects of transconductor design in the framework of current mode signal processing systems. Emphasis will be placed on large signal performance, with secondary consideration given to frequency response and noise. The chapter begins with an introduction to the mathematical techniques needed to characterize transconductor performance. Using these techniques, the large signal and small signal properties of the differential pair are analyzed. It will be shown that while offering excellent high frequency performance and low noise, its large signal characteristics are nonlinear. Therefore, the dynamic range and efficiency of the differential pair are limited.
