    Abstract: A voltage interpolation circuit includes a resistive ladder connected between ground and a voltage input and having a plurality of resistors with voltage taps between the resistors. An amplifier (optionally) has first and second capacitors connected together at their respective first terminals and to an input of the amplifier. A first plurality of switches connect respective taps to a second terminal of the first capacitor. A second plurality of switches connect the respective taps to a second terminal of the second capacitor. An output voltage is interpolated by controlling the first and second pluralities of switches.

    Abstract: In a latch circuit having a bistable pair of cross connected transistors of a first polarity and a third transistor of a second polarity, a current signal greater than a bias current is received at a latch circuit port, amplified with the third transistor, and applied to the latch circuit port. This decreases the time in which the latch circuit port receiving the current signal greater than the bias current reaches a steady state voltage.
