High voltage high speed amplifier using floating high side structure |
摘要 |
An integrated high-voltage linear amplifier IC with reduced power dissipation, faster operation, and small die size, comprising a low side well and a floating high side well; an error amplifier for receiving a noise signal; a level shifting circuit in the low side well for outputting a current mode error signal based on the noise signal to the high side well in differential current mode for noise reduction; and a drive circuit in the high side well. A voltage/current converter receives a voltage mode error signal based on the noise signal and supplies the current input signal. Current mirror circuitry and the drive circuit in the high side well outputs a sum current derived from the current mode error signal for driving external power devices.
