    摘要: There is provided an oscillator circuit in which an oscillation permitting signal (EN) sets an oscillator section (5) in an oscillation-operable state, whereby a controller section (4) starts operation. The controller section (4) that has started its operation changes an oscillation-frequency control signal (VR) value corresponding to a predetermined oscillation frequency so as to set an oscillation frequency at an oscillator section (5). Further on, the oscillator section (5) outputs an oscillation signal (VOSC) in response to a detection signal (MON) that is outputted after a detector section (1) compares a signal inputted therein with a predetermined signal value and detects that the inputted signal reaches a predetermined signal value. Thereby, a transient state of an oscillation-frequency control signal (VR) can be detected. That is, there can be avoided an output of an unstable oscillation signal due to a transient oscillation-frequency control signal (VR). Such an oscillator circuit is capable of obtaining stable frequency by avoiding output having unstable frequency that is likely to occur to an operation/stop-control-feasible type oscillator circuit when oscillation begins.

    摘要: A method of programming a programmable analog device architecture that introduces on a single chip a set of tailored analog blocks and elements that can be configured and reconfigured in different ways to implement a variety of different analog functions. The analog blocks can be electrically coupled to each other in different combinations to perform different analog functions. The architecture includes an array of analog blocks, including continuous time blocks and different types of switched capacitor blocks. Each analog block includes analog elements that have changeable characteristics that can be specified according to the function to be performed. Configuration registers define the type of function to be performed, the way in which the analog blocks are to be coupled, the inputs and outputs of the analog blocks, and the characteristics of the analog elements. The configuration registers can be dynamically programmed. Thus, the device can be used to realize a large number of different analog functions and applications.

    摘要: A new digital configurable macro architecture is described. The digital configurable macro architecture is well suited for microcontroller or controller designs. In particular, the foundation of the digital configurable macro architecture is a programmable digital circuit block. In an embodiment, programmable digital circuit blocks are 8-bit circuit modules that can be programmed to perform any one of a variety of predetermined digital functions by changing the contents of a few registers therein, unlike a FPGA which is a generic device that can be programmed to perform any arbitrary digital function. Specifically, the circuit components of the programmable digital circuit block are designed for reuse in several of the predetermined digital functions such that to minimize the size of the programmable digital circuit block.

    摘要: A voltage controlled oscillation circuit with an oscillation frequency thereof controlled in accordance with an external voltage is disclosed. An odd number of inversion circuit elements (1-1 to 1-(2n+1)) such as inverters for inverting output signals thereof with respect to input signals thereto are connected in series with each other. An output side of the last-stage one of the odd number of the inversion circuit elements (1-1 to 1-(2n+1)) is connected to an input side of the first-stage one of the inversion circuit elements (1-1 to 1-(2n+1)) to thereby cause an oscillation. A plurality of oscillation frequency variable control units (2-1 to 2-(2n+1)) such as variable resistor circuit elements for changing an oscillation frequency in accordance with an external voltage are each inserted between each set of adjacent inversion circuit elements. A plurality of fixed resistor circuit elements (3-1 to 3-(2n+1)) each having a fixed resistance value are connected in parallel with a plurality of the oscillation frequency variable control units (2-1 to 2-(2n+1)), respectively. The functions of both the variable resistor circuit elements and the fixed resistor circuit elements can be carried out at the same time by the use of a depletion type transistor or a transistor of a short channel type.
