An electronic circuit includes a differential input section, a current mirror section, an operational amplifier, an inverter, and a compensation voltage generator. The differential input section and the current mirror section are coupled together, forming a first common drain node and a second common drain node. The current mirror section has two p-type transistors coupled together at a common gate node. The operational amplifier has a positive input coupled to the first common drain node, a negative input coupled to the compensation voltage generator, and an output coupled to the common gate node. The inverter has an input node coupled to the second common drain node. The compensation voltage generator provides a compensation voltage to replicate a switching threshold voltage of the inverter. |
