摘要：

This paper presents a new Externally Linear Internally Nonlinear (ELIN) programmable gain amplifier (PGA). The topology was derived from a variable gain amplifier by using a current division network (CDN). The gain can be tuned by varying the DC bias currents. Simulation results demonstrate the analytical analysis.
