High efficiency bridge amplifier |
摘要 |
<p>Distorting effects and disturbances caused by abrupt voltage changes on the output nodes of a pair of selfconfiguring amplifiers for alternatively driving in a bridge mode or in a single-ended mode by one amplifier of the pair a certain load, in function of the level of the input signal, because of the enabling/disabling of a common mode control loop, are effectively eliminated by storing the voltage of a common mode control node of the pair of amplifiers on a capacitance during a phase of disabling of said common mode control loop. Abrupt voltage drops and recoveries at the switching instants are prevented. <IMAGE></p> |
