Front-End Chain Closes - Electronic Circuits V: Front-End Conditioning and Gain Contracts Step by Step

A full front-end chain carries one exact voltage through hold, gain, threshold, and load. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

The held node is amplified before the decision

The held input of 2 volts with gain 3 gives 6 volts.

V_{\text{gain}} = 3\cdot 2\ \text{V} = 6\ \text{V}

The HIGH rail drives a source and load

The output stage has a 4 volt source drop, leaving 8 volts across the load at 2 amperes.

V_{\text{load}} = 8\ \text{V}\qquad I = 2\ \text{A}
