Abstract
An integrated circuit device can include a radio-frequency device and a hard-wired lookup table. The radio-frequency device can have an analog input, a digital control input, and an analog output. An unadjusted transfer response of the analog output relative to the analog input and the digital control input can differ from an ideal transfer response. The hard-wired lookup table can be connected to the digital control input of the radio-frequency device to generate a modified digital control input based on a predetermined function. This can have the effect that the adjusted transfer response of the analog output relative to the analog input and the modified digital control input is closer to the ideal transfer response than the unadjusted transfer response of the analog output relative to the analog input and the digital control input. The predetermined function can be defined by metallization connections within the integrated circuit device.
