Methods, systems, and devices for configurable input for an amplifier are described. In some examples, a circuit may be configured to operate based on a signal having a first voltage profile or a second voltage profile. For example, the first voltage profile may be associated with a range of voltages that are based on a temperature of an associated memory chip, and the second voltage profile may be associated with a voltage (or voltages) that are not associated with the temperature of the memory chip. The circuit may include one or more transistors and switches that are activated based on the voltage profile and a switch receiving a particular control signal. In some instances, the control signal may be received based on a value stored to one or more non-volatile memory elements.

Configurable input for an amplifier

Methods and apparatuses are provided for temperature independent resistive-capacitive delay circuits of a semiconductor device. For example, delays associated with ZQ calibration or timing of the RAS chain may be implemented that to include circuitry that exhibits both proportional to absolute temperature (PTAT) characteristics and complementary to absolute temperature (CTAT) characteristics in order to control delay times across a range of operating temperatures. The RC delay circuits may include a first type of circuitry having impedance with PTAT characteristics that is coupled to an output node in parallel with a second type of circuitry having impedance with CTAT characteristics. The first type of circuitry may include a resistor and the second type of circuitry may include a transistor, in some embodiments.
