INTEGRATED CIRCUIT AND BATTERY POWERED ELECTRONIC DEVICE
摘要
<p>An integrated circuit ( 100 ) has a circuit portion ( 102 ) that can be switched to a standby mode through an enable transistor ( 104 ), which is coupled between an internal power supply line ( 120 ) and an external power supply line ( 130 ). The enable transistor ( 104 ) is controlled by control circuitry via a control line ( 160 ). The control line ( 160 ) is coupled to the gates of a first transistor ( 152 ) and a further transistor ( 154 ) of a logic gate ( 150 ). The substrate of the further transistor ( 154 ) is coupled to a backbias generator ( 170 ). Consequently, when the enable transistor ( 104 ) is switched off, the further transistor ( 154 ) is enabled and applies a substantial backbias to the gate of the enable transistor ( 104 ), thus dramatically reducing the leakage current from the circuit portion ( 102 ) through the enable transistor ( 104 ).</p>
