20080265978 | Tuning capacitance to enhance FET stack voltage withstand - 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. | 10-30-2008 |
20100033226 | Level shifter with output spike reduction - A level shifter, or method, producing a final output from a driver supplied by a high-side source driver providing VDD or common, and a low-side source driver providing common or VSS. A delay is introduced to prevent a source driver output at common from beginning to transition toward a supply rail until a delaying source driver at a rail begins transitioning toward common. The level shifter may be single-ended or differential, and the delaying source driver may be coupled to the same final output driver as is the delayed source driver, or may be coupled to a different final output driver. The level shifter may have a second level shifter front end stage, which may have high-side and low-side intermediate source driver outputs coupled by a capacitor, and/or may couple one of the supplies to all intermediate source drivers via a common impedance or current limit Zs. | 02-11-2010 |
