Abstract

Commonly used elementary circuits like single transistor amplifier stages, the differential pair and current mirror basically exploit the transconductance of transistors. This paper aims at finding ALL elementary transconductance based circuits. For this purpose, all graphs of two-port circuits with one or two Voltage Controlled Current Sources (VCCS) are generated systematically. This leads to 150 graphs. Each of them can be implemented in various ways using transistors and resistors, covering most commonly required types of two-ports. A new Low Noise Amplifier (LNA) implemented in 0.35 μm CMOS illustrates the usefulness of the technique
