Abstract:
A transceiver apparatus, comprising:a transmitter portion for transmitting information;a receiver portion for receiving information, the receiver portion being switchable between a low power consumption mode and an active mode; anda control circuit coupled to the receiver portion for selectively switching the receiver portion from the low power consumption mode to the active mode in response to detecting an information signal to be received by the receiver while in the low power consumption mode, whereby the receiver portion receives the information signal in the active mode;wherein the receiver portion includes power-consuming components that are selectively activated in the active mode but not activated in the low power consumption mode and power-consuming components that are activated in both the low power consumption mode and the active mode;wherein the supply of power to the power-consuming components that are not activated in the low sower consumption mode is reduced during the low sower consumption mode and increased during the active mode; andwherein the supply of power is maintained to the power-consuming components that are activated in both the low power consumption mode and the active mode during the low power consumption mode and in the active mode.
