Patent ID: 8516410

Claim:
A method of migrating an electronic circuit incorporating a plurality of analog devices from a source technology to a target technology, the method comprising: loading said electronic circuit to be migrated from said source technology to said target technology; determining small-signal parameters and biasing conditions of devices in said electronic circuit; for each device, identifying voltage sensitive ports and voltage insensitive ports; for each node in said electronic circuit, counting the number of devices connected via a voltage sensitive port to a circuit node and the number of devices connected via a voltage insensitive port to the circuit node; defining as a voltage tuning node of said electronic circuit those circuit nodes to which a device is connected via a voltage sensitive port while all additional devices connected to the circuit node are connected via a voltage insensitive port; identifying devices that are connected to a voltage tuning node via voltage sensitive port as devices operating in current mode conditions, wherein each identified device is connected to its respective voltage tuning node via a voltage sensitive port, whereby permitting a change in voltage at said voltage tuning nodes yields a degree of freedom in addition to that provided by the length and width of devices in said electronic circuit due to the current in current mode devices being relatively insensitive to port voltage at voltage tuning nodes; for all devices operating in current mode conditions, resizing each said identified device from said source technology to said target technology, to yield adjusted device sizes, taking into account that each identified device operates in current mode conditions and wherein both the geometry of the identified device and the voltage at the voltage tuning node connected to the identified device via the voltage sensitive port of the identified device are modified to achieve performance goals; and replacing each said identified device in said electronic circuit with its respective said resized device, thereby creating a target electronic circuit in said target technology.
