Abstract: Embodiments are provided for biasing circuits with compensation of process variation without band-gap referenced current or voltage. In an embodiment, a circuit for biasing a field-effect transistor (FET) passive mixer comprises a series of diode-connected FETs, and a series of first resistors connected to a voltage source and the series of diode-connected FETs. Additionally, one or more second resistors are connected to the series of diode-connected FETs and to ground. In an embodiment method, the total number of the diode-connected FETs and the total number of the resistors, including the first and second series of resistors, are selected. The total number of the second resistors is then determined according to a defined relation between the selected total number of diode-connected FETs and the total number of resistors.
