Abstract: Circuitry for monitoring the operation of an optoelectronic transceiver includes a sequence of interconnected signal processing circuits for processing an analog input signal and producing a digital result signal, where the analog signal represents one or more operating conditions of the optoelectronic transceiver. The sequence of signal processing circuits include gain circuitry for amplifying or attenuating the analog input signal by a gain value to produce a scaled analog signal, an analog to digital converter for converting the scaled analog signal into a first digital signal, and digital adjustment circuitry for digitally adjusting the first digital signal to produce the digital result signal. The digital adjustment circuitry includes shifting circuitry configured to shift an input digital signal in accordance with a shift value so as to produce a digital shifted signal. The digital result signal is stored in memory in predefined locations accessible by a host.

Abstract: Microcode driven adjustment of analog scaling of an analog signal prior to being provided to an analog-to-digital converter. The microcode also causes the system to read the resulting digital value, and determine whether the scaling value should be adjusted for that analog signal. Accordingly, the microcode may cause the analog signal to be dynamically adjusted to be within the input range of the analog-to-digital converter, thereby allowing for more accurate digital conversions with lower resolution analog-to-digital converters. The microcode rapidly adjusts for any fluctuations in the input voltage. Accordingly, the analog signal may fluctuate, or even be multiplexed from a wide variety of different analog signal sources.

Abstract: An optical component is provided that includes a detector configured to transmit an input current to a transimpedance amplifier that includes an automatic transimpedance gain control and DC cancellation control feedback circuit having variable impedance circuitry. Open loop gain of the feedback circuit is independent of the average input current as the input current increases. The feedback circuit includes first and second pnp transistors arranged so that their respective bases are connected and so that an emitter terminal of the first pnp transistor is connected to the input of the transimpedance amplifier, and the impedance seen at the emitter terminal changes according to the average value of the input current. The emitter size of the second pnp transistor is a factor N smaller than emitter size of the first pnp transistor. N can be selected to adjust the gain control and low corner frequency variation with input power.

Abstract: A micro-power, micro-size RF detector is suitable for implementation on an integrated circuit. The detector is used for detecting the presence of high frequency AC signals on a transmission line which has a transmission line impedance. An input for connection to the transmission line through a high impedance relative to the transmission line is provided. A current mode detector is coupled to the input. The current mode detector translates AC signals on the input to a bias signal having a DC component determined by power of the AC signal on the transmission line. A current mode amplifier is coupled to the current mode detector, and amplifies the bias signal to produce a detector current. A binary output driver is coupled to the current mode amplifier, which generates a binary signal having one binary level if the detector current exceeds a high signal threshold, and another binary level if the detector current falls below a low signal threshold.
