Abstract: Methods and devices for leakage current reduction are described. A regulator transistor is connected to a switch to bias the transistor with a first voltage during an ON state and a second voltage during the OFF state of the transistor. The switchable bias allows leakage current decrease and “on” resistance increase of the transistor.

Abstract: A method and apparatus for initiating a reverse link intergenerational handoff in a CDMA communication system that measures and compares parameters between a serving base station of one generation and a target base station of another generation to determine the best possible handoff initiation time instant for performing a reverse link intergenerational hard handoff. Different embodiments can utilize one of several procedures to determine the best possible handoff initiation time instant. A pilot signal strength embodiment determines a handoff initiation time instant based upon the total pilot signal strength of both a serving and target base station. An Eb/Nt embodiment determines a handoff initiation time instant based upon Eb/Nt (ratio of average power per bit to total received power spectral density) values of both a serving and a target base station. The method and apparatus decreases the probability of degraded or dropped calls during intergenerational handoffs.
