Programmable gain voltage buffer |
摘要 |
A programmable gain voltage buffer circuit with a programmable gain may include transistors in parallel with resistors. The transistors may be used as variable resistors, with the resistors predominating the equivalent resistances at output points in different branches of the buffer circuit. The transistors may have resistances corresponding to programmable gain steps in the circuit.
