    摘要: Switch circuits are disclosed, for providing a single-ended and a differentially switched high-voltage output signals by switching a high supply voltage in response to at least one logic-level control signal. The switch that provides the single-ended switched high-voltage output signal includes a chain of at least three serially coupled field effect transistors (FETs). The chain receives the high supply voltage and switches it to output the high-voltage output signal. The switch that provides the differentially switched high-voltage output signal includes two differentially coupled chains, each having at least three serially coupled FETs. The chains receive the high supply voltage and switch it to output the differential high-voltage output signal. A control/bias circuit provides a control voltage to at least one of the FETs in the chains, responsive to the control signal.

    摘要: An OTP bit cell includes a latch circuit of cross-coupled inverters. A floating gate PMOS transistor is inserted in each of the inverters. One or the other of the floating gate PMOS transistors is programmed through an included programming circuit so that a differential output of the latch circuit provides a corresponding logic state that is the same each time when read. To program a selected floating gate PMOS transistor, appropriate write inputs are applied to the programming circuit while a high reference voltage to the OTP bit cell is raised to a level such that the selected floating gate PMOS transistor is programmed.

    摘要: A low standby current power-on reset circuit is described. A first NMOS transistor's drain is coupled to a first PMOS transistor's drain; source coupled to ground line; and gate coupled to a first capacitor coupled to ground line. The first PMOS transistor's source is coupled to power line; gate coupled to second capacitor coupled to ground line; and drain provides a power-on reset indication. A second PMOS transistor's source is coupled to power line; drain is coupled to drain of second NMOS transistor, gates of first PMOS, second PMOS, and second NMOS transistors, and second capacitor. The second NMOS transistor's source is coupled to gate of first NMOS transistor and first capacitor. A discharge circuit is coupled to power line, ground line, and first and second capacitors for discharging the capacitors when a voltage on power line drops below a level determined by the second PMOS transistor's threshold voltage.
