  • Stepped delay control of integrated switches
    Patent number: 8710899
    Abstract: An integrated switching device, such as an RF attenuator, can be controlled to be in various states according to control bits of a control signal. The integrated switching device can be gradually transitioned from one state to another by staggering the timing of changing the control bits. Latch-up problems in the integrated switching device can thereby be reduced or prevented.
    Type: Grant

  • Circuits and methods for implementing approximations to logarithms
    Patent number: 7266576
    Abstract: A method for approximating a base 2 logarithm of a binary input and the circuit to implement the method are disclosed. The circuit comprises means for determining the integer portion of the logarithm, a lookup table module, a residual function module, an adder module and a register. This circuit performs the approximation in one system clock cycle time.
