A method may include reconfigurably enabling one of a first downconverter and a second converter and disabling the other the second downconverter, wherein the first downconverter and the second downconverter are integral to a receiver unit of as wireless communications terminal. The method may also include frequency downconverting received wireless communication signals by the enabled downconverter. The method may also include processing the downconverted wireless communication signals by a primary path if the first downconverter is enabled, and processing the downconverted wireless communication signals by a diversity path if the second downconverter is enabled.

Reconfigurable diversity receiver

A frequency divider with a twenty-five percent duty cycle is disclosed. A frequency divider may include an input configured to receive a clock signal, each cycle of the clock signal including a first phase and a second phase, a plurality of latches, and a plurality of three-state circuits wherein a first of the plurality of three-state circuits is configured to drive a first twenty-five percent duty cycle signal from within the first three-state circuit high during a first phase of a first of two clock cycles.

Technique to generate divide by two and 25% duty cycle

A technique for improving the linearity of a mixer is disclosed. A converter may include a mixer comprising a first metal-oxide semiconductor field-effect transistor (MOSFET) having a gate, a first conducting terminal coupled to an input of the converter, and a second conducting terminal coupled to an output of the converter, and a mixer driver having a first output coupled to the gate of the first MOSFET, the mixer driver configured to receive a local-oscillator signal having a first phase and a second phase, drive the first MOSFET off during the first phase of the local-oscillator signal, drive the first MOSFET on for a first period of time in response to a transition from the first phase of the local-oscillator signal to the second phase of the local-oscillator signal, and force the gate of the first MOSFET into a high impedance state for a second period of time during the second phase of the local-oscillator signal and after the expiration of the first period of time.
