Analog Circuit Design with Linearized DC Biasing

A new methodology is presented for the design of analog ICs. The method is based on a locally-biasing technique that DC-nullifies the ports. This entirely removes the general biasing of the circuit and applies it on each nonlinear devices individually. The method isolates the nonlinear devices from the rest of the circuit, and excludes them from the design procedure. It allows the circuit designer to select the optimal operating regions for the devices, and then start working on the rest of the (linear) circuit with no need to perform nonlinear iterations or to worry about a possible divergence. An example of an operational amplifier design demonstrates the procedure
