Abstract
High performance voltage reducers were developed for ultra low-power battery operated systems in which several parts need a supply voltage adapted dynamically in order to optimize the energy consumption. Above 90% efficiency has been obtained for a 6 mA output current with a sliding mode Buck converter using a miniature external inductor; a very simple current mode approach has been proposed for this converter. Linear dissipative voltage regulators are used to supply very low duty cycle parts; their dynamic behavior for large and fast load variation has been improved adding the derivative of the regulated voltage to the control signal.
