摘要： An optical disk system includes at least one photo detector connected with a variable gain amplifier, a slicer, and a generator which is in the feedback path between the slicer and amplifier. A differential time delay detector provides the output of the optical disk system. The generator is configured for controlling the amplifier non-linearly so that time constants of the control loop of the amplifier which depend upon the level of the input signals are compensated and the timing behavior of the control loop of the amplifier has a more continuous character. A capacitor forms part of an integrator for making the mean value of the output voltage signal of the slicer equal to zero.

摘要： Optical disk systems comprising photo detectors (1) for detecting optical disks comprising amplifiers and slicers (2-5) and delay-difference detectors (6) for detecting delay differences in sliced amplified detection signals are improved by installing delaylineless delay-difference detectors (6) comprising combinatorial-logic circuits (7,8) like inverters, ORs, NORs, ANDs, NANDs and sequential-logic circuits (11-18) like SetResetFlipFlops. Without the prior art delay lines, said delay-difference detectors (6) are of a lower complexity and low costly and can be well integrated. By introducing a first pair of sequential-logic circuits (11,12,15,16) for detecting delay differences between rising edges and a second pair of sequential-logic circuits (13,14,17,18) for detecting delay differences between falling edges, both kinds of edges are being used and the influence of time-jitter is less compared to the situation where just one kind of edge is used. Said delay-difference detector (6) further comprises an analog adder/subtracter (9) for adding/subtracting-logic circuit output signals and low pass filter(s) (10) located before or after said adder/subtracter (9).

摘要： An electronic circuit is provided which can autonomously handle an input current (Ii) having a relatively wide dynamic range without being overdriven. The electronic circuit comprises an amplifier stage (AMPST) having an input (IP) for receiving the input current (Ii) and an output (OP) for supplying an output current (Io), such that, during operation, the strength of the output current (Io) increases in response to an increasing strength of the input current (Ii) as long as the strength of the input current (Ii) has not exceeded an input reference level. The strength of the output current (Io) is kept approximately constant when the strength of the input current (Ii) has exceeded the input reference level but has not exceeded a further input reference level. The strength of the output current (Io) decreases in response to an increasing strength of the input current (Ii) when the strength of the input current (Ii) has exceeded the further input reference level. The amplifier stage (AMPST) may comprise a current mirror (CM) having an input which forms the input (IP), an output which forms the output (OP), and a common node (cn). The amplifier stage (AMPST) further comprises first control means (FCM) having an input connected to the input (EP), and an output connected to the common node (cn). First control means (FCM) controls a current (I2) to the common node (cn) and a voltage (Vcn) at the common node (cn). The first control means (FCM) comprises limiting means (LMT) for limiting the current (I2) when the value of the input current (Ii) has exceeded the input reference level. Then both the input and the output currents (Ii and Io) are limited. In order to avoid a saturation situation of a current source (Is) which supplies a current (I) to the input (EP), the amplifier stage (AMPST) may comprise second control means (SCM) for supplying a compensation current (ICMP) to the input (IP) when the input signal (Ii) has exceeded the input reference level. The current mirror (CM) comprises first (CP1) and second (CP2) current paths which form the core of the current mirror (CM), as is generally known. The decrease in response to an increasing strength of the input current (Ii) when the strength of the input current (Ii) has exceeded the further input reference level is implemented by a third current path (CP3) which takes away current from the second current path (CP2). Optionally, to avoid that the value of the output current (Io) can become too low, a fourth current path (CP4) may be implemented which applies current to the second current path (CP2). The inventive electronic circuit may be advantageously applied in all electronic systems (like CD-apparatus) which need means to limit a maximum output signal.
