Patent number: 9806405Abstract: An integrated circuit for use in remote keyless entry (RKE) applications is disclosed that integrates two drivers with a shared dual mode antenna. The drivers may be integrated on a single integrated circuit chip using high voltage (HV) complementary metal-oxide-semiconductor (CMOS) processes. In immobilizer mode of operation, an immobilizer driver coupled to the dual mode antenna is configured to drive the dual mode antenna, while an LF mode driver coupled to the dual mode antenna is configured to be idle. In LF mode of operation, the LF mode driver is configured to drive the dual mode antenna, while the immobilizer driver is configured to be idle. In some implementations, the drivers are coupled to a common node coupled to the dual mode antenna and are selectively biased with different supply voltages based on the current mode of operation to prevent current leakage and component damage.Type: GrantFiled: January 31, 2013Date of Patent: October 31, 2017Assignee: Atmel CorporationInventors: Thorsten Fahlbusch, Marco Schwarzmueller, Juergen Schnabel

Patent number: 7129788Abstract: A d.c. signal controlled oscillator includes a frequency-determining network having a control input and a modulation input. A phase regulating loop includes the oscillator and components that provide a control signal to the control input. A circuit apparatus for driving the oscillator includes a modulation generator that provides a modulation signal to the modulation input, and a circuit arrangement that autonomously generates a signal depending on and representing a slope of the modulation and provides this slope signal to the modulation generator, which generates the modulation signal dependent on the slope signal.Type: GrantFiled: April 27, 2004Date of Patent: October 31, 2006Assignee: Atmel Germany GmbHInventors: Juergen Eckert, Thorsten Fahlbusch, Burkhard Gehring, Hans-Werner Groh, Horst Haefner, Hermann Hammel, Michael Hecker, Gerald Krimmer, Reinhard Reimann, Wolfgang Roeper, Friedemann Schmidt, Juergen Schnabel, Wolfgang Schneider, Michael Vogt, Hans-Peter Waible

Patent number: 6525604Abstract: A control unit and two negative feedback branches limit the amplitudes of the output signal of an inverting differential amplifier. Each feedback branch includes a threshold value switch including a transistor as well as an adjustable current source and a resistor forming a voltage divider between a supply voltage and the amplifier output. The voltage divider output is connected to the transistor's base. The transistor selectively connects or disconnects the input of the amplifier with either the supply voltage or the amplifier output. The control unit controls the two current sources based on external programming commands, to establish two adjustable threshold values within which the negative and positive amplitudes of the output signal are limited, symmetrically or independently, in a hard or soft clipping manner. Even with small supply voltages, the limited output will not overdrive subsequent amplifier input stages and will not superimpose harmonics on the useful signal.Type: GrantFiled: March 27, 2002Date of Patent: February 25, 2003Assignee: ATMEL Germany GmbHInventors: Juergen Eckert, Juergen Schnabel
