Abstract: The present disclosure describes a system that can include an antenna; a receive (Rx) path coupled to the antenna; and a transmit (Tx) path comprising a balun; and a radio frequency (RF) attenuator comprising a first port and a second port, the balun coupled to the first port, the antenna coupled to the second port. The RF attenuator can include a first switch coupled between the first port and the second port; a second switch and a first attenuator coupled to each other in series between the first port and the second port, the first attenuator having a first attenuator value; and a third switch and a second attenuator coupled to each other in series between the first port and the second port, the second attenuator having a second attenuator value greater than the first attenuator value of the first attenuator.

Abstract: Disclosed herein are related to systems and methods for correcting non-linearity due to duty cycle error. In one aspect, a system includes a mixer configured to up-convert transmission (Tx) data, a coefficient calibrator configured to select a target value of a coefficient based on a measurement of an interference signal due to non-linearity of the mixer, and an interference canceller coupled to the coefficient calibrator and the mixer. In some embodiments, the interference canceller is configured to generate compensated Tx data based on the Tx data and the selected target value of the coefficient and provide the compensated Tx data to the mixer. In some embodiments, the compensated Tx data corrects for the non-linearity of the mixer.

Abstract: Disclosed herein are related to systems and methods for selectively disabling current steering circuitries. In one aspect, the system includes a balun including a first inductor and a second inductor, a first current steering circuit coupled to the first inductor, a second current steering circuit coupled to the first inductor, and a controller coupled to the first current steering circuit and the second current steering circuit. In one aspect, the controller is configured to, based on input data having a first state, apply a first signal and a second signal having a first level to the first current steering circuit and a third signal and a fourth signal having the first level to the second current steering circuit to disable a first current through the second inductor, a second current through the first current steering circuit, and a third current through the second current steering circuit.

Abstract: A high-speed, low leakage-power Standard Cell Library is provided. The high-speed, low-leakage-power Standard Cell Library provides the extra drive-strength of a taller X-Track library (e.g., 14-Track library) and low leakage-power comparable to that of a smaller, N-Track library (e.g., 10-Track library). The high-speed, low leakage-power Standard Cell Library includes a set of cells each having a device area designed to provide maximum drive strength for the cell. The high-speed, low leakage-power Standard Cell Library further includes a second set of cells having varying device areas that provide reduced leakage power characteristics comparable to cells in the smaller, N-Track library. The modified reduced leakage-power cells are formed by adding padding to the cell to achieve a desired leakage-power characteristic of the cell.
