Abstract: A differential amplifier includes an input pair of transistors with a source-side resistor circuit, having a transistor biased in a triode region, and a current source. The resistor circuit in combination with a capacitance, causes source degeneration in the amplifier. The source side resistor circuit includes a first MOS transistor having a first channel terminal connected to the source of a first transistor in the differential pair, and a second channel terminal connected to the bulk terminal, and a second MOS transistor having a first channel terminal connected to the source of a second transistor in the differential pair, and a second channel terminal connected to the bulk terminal. A bias circuit biases the first MOS transistor and the second MOS transistor in a triode region. The resistance of the source-side resistor circuit and the gain of the transistors in the differential amplifier can track across process corners.

Abstract: Disclosed is a semiconductor device that has a first layer including conductive material, a bond wire coupled to an upper surface of the first layer, and a second layer including conductive material underneath the first layer. One or more interconnects couple the second layer to the first layer.

Abstract: An integrated circuit with a power-on-reset circuit includes an inverter circuit connected between the first and second supply node, a cascode-connected series of transistors MCn, for n going from 1 to N, connected between the first supply node and the input node of the inverter, and a resistive element connected between the input node of the inverter and the second supply node. The transistors in the cascode-connected series of transistors MCn pull up the input node voltage above a trip point voltage when the voltage between the input node and the first supply node is more than a threshold of the cascode-connected series. A circuit connected between the first and second supply nodes is responsive to a POR pulse output by the inverter.
