> Un the middle of the range both MOSFETs are likely conducting, effectively producing a dead short! This is exactly the configuration described in the CD4069UBE datasheet, where single stages of the hex inverter are biased to the midpoint with a feedback resistor. This turns them into a surprisingly good programmable inverting amplifier, rather like an opamp without a non-inverting input. |
