Figure 1 shows the variable gain amplifier (OPA660) circuit chart 1 The OPA660 OTA transconductance gm and static current Io the approximate relationship table. The figure shows the circuit using transconductance op-amp integrated amplifier amplification OPA660 chip as components. The OPA660 integrated chips internal circuit has two components: The transconductance amplification and caching OTA part. About the internal structure of the integrated chips OPA660, the feet and the main parameters of the relevant material. The figure below is the table of the OPA660 OTA transconductance of gm and static current Io approximate relationship.
