Abstract: A charge pump is connected between a source and a body of the switch. Such a configuration avoids a condition in which the body diode opens for negative drain-to-source voltage (Vds) across the switch. Such a configuration also avoids a condition in which the switch control circuit generates control signals referenced to a body potential rather than a source potential, thereby allowing the switch to reliably turn off even for negative Vds. An additional gain stage ensures that the switch can be properly turned on. The techniques can be used to generate switches that enable highly linear processing of bipolar differential signals even far outside of the supply range.

Abstract: A hybrid converter achieves high efficiency with an inductor positioned at the lower current path that significantly decreases inductor loss by having the DC component of inductor current reduced. The circuit also features reduced inductance requirement by reducing the voltage swing blocked by the inductor. As a result, it turns to benefit of both efficiency improvement and better integration.

For simplicity and cost, some of switches can be replaced with passive switches such as diodes which highly simplifies the converter circuit implementation.
