Abstract: An RF switch to controllably withstand an applied RF voltage Vsw, or a method of fabricating such a switch, which includes a string of series-connected constituent FETs with a node of the string between each pair of adjacent FETs. The method includes controlling capacitances between different nodes of the string to effectively tune the string capacitively, which will reduce the variance in the RF switch voltage distributed across each constituent FET, thereby enhancing switch breakdown voltage. Capacitances are controlled, for example, by disposing capacitive features between nodes of the string, and/or by varying design parameters of different constituent FETs. For each node, a sum of products of each significant capacitor by a proportion of Vsw appearing across it may be controlled to approximately zero.

Abstract: Circuits and methods that compensate for the problems created by low-dropout regulator (LDO) leakage current, particularly when stressed. Embodiments include an improved LDO configured to provide a load current, and which includes a leakage current compensation circuit. The leakage current compensation circuit generates a compensating current that offsets the leakage current through the pass device of the LDO during conditions that induce such leakage. More specifically, the leakage current compensation circuit can replicate the leakage current of the pass device of the LDO and feed a compensating current back into the LDO from a current mirror circuit while drawing zero-power during normal use, when leakage current is absent. LDO circuits that include a leakage current compensation circuit are particularly useful as voltage sources for positive or negative charge pumps, but are also quite useful in applications requiring a regulated voltage output.
