Abstract: An enhanced current mirror can be utilized to accurately control a bias current associated with an amplifier. A current controller component (CCC) can employ the enhanced current mirror and can be associated with the amplifier. The CCC can comprise a comparator that can compare an adjusted supply voltage level to a reference voltage level, the adjusted supply voltage level relating to a supply voltage level of a supply voltage supplied to the amplifier and CCC. The CCC can control switching of an operational state of a transistor of the comparator to switch in or out a resistance of a reference resistor component associated with the supply voltage, based on a result of the comparison of the adjusted supply voltage level to the reference voltage level, to facilitate accurately controlling an amount of bias current associated with the amplifier. The CCC and amplifier can be situated on the same die.

Abstract: Systems, circuits, and methods for mixing signals are provided. An illustrative circuit may include mixer circuitry including multiple inputs and at least one output, where the multiple inputs are connected across a local oscillator. The circuit may further include a terminal Radio Frequency (RF) output circuitry that is isolated from the local oscillator, where the at least one output of the mixer circuitry is directly connected to an input of the terminal RF output circuitry. The circuit may further include terminal Intermediate Frequency (IF) output circuitry that is isolated from the local oscillator, where the at least one output of the mixer circuitry is directly connected to an input of the terminal IF output circuitry.
