Use of local biasing in designing analog integrated circuits

—A new biasing technique called “local biasing” of transistors is used to design analog integrated circuit amplifiers, or any other analog ICs. The technique is based on designing the circuit without any external source but only the sources that are used to locally bias the transistors [12, 13]. Later these sources are transferred to appropriate locations in the circuit which leads the circuit to a new topology and configuration that makes it possible to replace the local biasing sources with final current mirrors and one or two conventional power supplies. Local biasing is revisited, and an OTA design example is provided to clarify the methodology and demonstrate the procedure.
