Operational amplifier having an adjustable frequency compensation |
摘要 |
An integrated operational amplifier with adjustable frequency compensation having a transconductance input stage and an amplifier output stage connected serially together between an input terminal and an output terminal of the operational amplifier. For the purpose of frequency compensation, moreover, a compensation block is connected across the input and the output of the output stage. The compensation block uses a plurality of charge storage elements connected in parallel together and in series with switch block which selects a sub-plurality of said charge storage elements in response to an external signal of the amplifier. The compensation block thereby provides an overall effective capacitance for frequency compensation.
