摘要： A bias current is generated for an unbalanced differential pair that is proportional to the transconductance gain of the differential pair. When the transconductance gain varies (e.g., due to temperature variations), the bias current varies in proportion thereby maintaining a constant offset voltage. In some implementations, a voltage to current converter circuit generates the bias current from a constant reference voltage that is independent of temperature and voltage supply variations (e.g., a bandgap reference voltage).

摘要： This document discloses low variation resistor devices, methods, systems, and methods of manufacturing the same. In some implementations, a low-variation resistor can be implemented with a metal-oxide-semiconductor field-effect-transistor (“MOSFET”) operating in the triode (e.g., ohmic) region. The MOSFET can have a source that is connected to a reference voltage (e.g., ground) and a gate connected to a gate voltage source. The gate voltage source can generate a gate voltage that varies in proportion to changes in the temperature of an operating environment. The gate voltage variation can, for example, be controlled so that it offsets the changes in MOSFET resistance that are caused by changes in temperature. In some implementations, the gate voltage variation offsets the resistance variance by offsetting changes in transistor mobility that are caused by changes in temperature.
