Abstract: A detection circuit for receiving a pair of unstable input signals along a pair of input leads and providing a stable output signal along an output lead, preferably to downstream circuitry. The detection circuit includes a plurality of transistors including a first transistor and a second transistor, wherein at least one of the first and second transistors is configured to turn on upon the detection circuit receiving input signals along the pair of input leads. At least one of the first and second transistors is configured to provide a signal along a lead to circuitry which is configured to condition the output signal and turn on a third transistor. The third transistor is connected to the first and said second transistors such that when the third transistor turns on, the third transistor prevents the first and second transistors from turning on until a new clock signal is received by the detection circuit.

Abstract: An on-chip voltage reference supply operates in the current domain rather than the voltage domain, implemented with a single diode drop to reduce power supply headroom requirements. A plurality of current generators generate currents representing a first design voltage. A gain circuit responds to the currents to supply a gain voltage representing the sum of the first design voltages. A summing circuit sums the gain voltage and a second design voltage to derive the predetermined reference voltage.
