Abstract
A monolithic radio integrated circuit includes a substrate, a set of one or more analog subcircuits on the substrate, a programmable bias current supply on the substrate coupled to the set to provide bias currents to the analog subcircuits of the set including programmable bias currents to one or more analog subcircuits forming a first subset of the set, and a digital subsection coupled to the programmable bias supply to determine the bias currents supplied to the analog subcircuits of the first subset, such that one or more characteristics of the radio integrated circuit are modifiable by programming the programmable bias supply.
Claims18
A radio frequency (RF) integrated circuit comprising:
- a substrate;
- a set of one or more analog subcircuits on the substrate;
- and
- a programmable bias current supply on the substrate coupled to the subcircuit set to provide bias currents to the analog subcircuits, including providing programmable bias current to each of one or more analog subcircuits forming a first subset of the set,
- such that one or more characteristics of the RF integrated circuit are modifiable by programming the programmable bias supply.
A method of calibrating a radio frequency (RF) integrated circuit (IC), the IC including:
- a substrate;
- a set of one or more analog subcircuits on the substrate;
- and
- a programmable bias current supply on the substrate coupled to the subcircuit set to provide bias currents to the analog subcircuits, including providing programmable bias current to each of one or more analog subcircuits forming a first subset of the set;
- the method comprising modifying the bias to one or more of the analog subcircuits to modify one or more characteristics of the IC, such that the IC meets a specification.
