    Abstract: A double cascode protected switchable voltage source may be used to selectively provide positive or negative voltage sources, for example, to a flash memory. The positive supply may be connected through a PMOS pass device to a first cascode protection device. A negative supply may be connected through an NMOS pass device and an NMOS cascode protection device to an output. The circuits may be designed so that exceeding snapback limits and gate aided drain breakdown are less likely.

    Abstract: A negative switch may enable switching of two different negative voltages. The switch may include a negative cascode bias generator which biases the gate of a cascade protection device. When the negative switch is passing a large negative voltage, the bias generator generates a lowered voltage to provide a cascade voltage for snapback protection of a passing transistor. When a relatively low negative voltage is to be switched, the bias generator may produce a positive voltage greater than the threshold voltage of the cascode protection device so that both high and low negative voltages may be switched by the same circuit without exposing the passing device to a voltage in excess of its snapback limit.

    Abstract: The present invention relates to novel polyketides, host cells that produce the novel compounds, and methods fort their use. The compounds of the present invention are cyclic polyketides (also referred to as a “macrolides” or “macrolactones”) that include as part of their structure and bind to a FK binding protein wherein R4 and R5 are each selected from the group consisting of hydrogen, methyl, ethyl, and methoxy, provided that at least one of R4 and R5 is hydrogen, methyl, or ethyl. As will be explained in greater detail below, the compounds of the present invention have properties such as favorable P450 enzyme activity profiles that are desirable for use of these compounds as drugs.
