Usually, this topology is considered as a voltage divider but it can be thought also as a 2-input resistor summing circuit with weighted inputs that sums VDD and 0 V (ground) or VEE, in the case of a split supply. Technically, the gate-source resistance is higher in the MOSFET due to the insulated gate, and this is useful in specific applications such as in the design of electrometers, but for general purpose work it is a minor distinction. However, as the operating frequency increases above 20 GHz, a single stage LNA cannot provide enough gain. Suitable design methods which involve changing of device parameters are suggested to aid noise reduction and hence design the amplifier with reduced noise characteristics. The demands on the design require a multitude of requirements to be taken into account. This LNA is designed to have three common source stages (LogOut/ Chapter 9Transimpedance Amplifier Circuit Examples In the following, we examine some representative transistor-level TIA circuits taken from the literature. If I redraw it, perhaps it makes it more obvious: In a small signal sense, a NMOS CS amplifier is no different to a PMOS CS amplifier, so a parallel connection will simply give you a combined transconductor. The differential pair we studied in chapter 12, in Bipolar or FET form, is the most popular input stage for what are most often referred to as voltage feedback amplifiers VFB. Initially, the load is a resistor, then the load is a PMOS transistor acting as a current "source" (i.e., dynamic resistor) - Fig. They are common-source, common drain source-follower , and common-gate amplifier circuits.
