Title: Semiconductor laser driving circuit
IPC: H01S5/042
Filed: 1990-03-01
Abstract: A semiconductor laser driving circuit is arranged 
so that a predetermined number of transistors (14) can be 
selected from a group of transistors (12) disposed in 
parallel according to the characteristics of a 
semiconductor laser and the selected transistors (14) are 
connected in parallel between the semiconductor laser (1) 
and a current source (3). An optimum current is allowed 
to flow through the semiconductor laser (1) to cause it to 
generate a required light output. Moreover, a 
collector current which provides the optimum 
characteristics flows through each of the selected 
transistors (14). Therefore, an optimum high-speed 
response can always be realized irrespective of the 
magnitude of the driving pulse current of the 
semiconductor laser (1).

Abstract: It is an abject to stably and surely perform protection operation of devices.
Since the gate threshold voltage V GE(th)S   
in a sense IGBT cell constituting a sensing circuit is set to have a higher value than
the gate threshold voltage V GE(th)M  in a main IGBT cell constituting a main circuit,
a finite time Δt is required from when the gate voltage V GE  reaches the gate
threshold voltage V GE(th)M  until when it reaches the gate threshold voltage V GE(th)S 
in the turn-on period. Accordingly, the rise of the main current Is of the sensing
circuit is delayed from the main current Im of the main circuit. As a result, surge
current does not appear in the current Is. As the surge current does not appear in
the main current of the sensing circuit, a protection circuit of the device operates
stably, and breakdown of the device is surely prevented.

IPC: H04L27/227
Filed: 1995-11-27
Abstract: A signal acquisition system rapidly acquires carrier phase and symbol timing of a
received PSK-modulated communication signal (24) having a 110-symbol pattern through
joint estimation of carrier-phase adjustment and symbol-timing adjustment by processing a
common set of sampled data. A reference signal (22) at a local oscillator frequency is
mixed with a received communication signal (24) to provide the communication signal
(26) at an intermediate frequency. The intermediate-frequency communication signal (26)
is converted into a digital communication signal (28), which is formatted into in-phase (I)
and quadrature-phase (Q) components. A sampling circuit (18) samples the I components
at twice a predetermined symbol rate to provide a first series of I-component samples at
the predetermined symbol rate and a second series of I-component samples that are
intermediate to the first series of I-component samples and at the predetermined symbol
rate, and for sampling the Q components at twice the predetermined symbol rate to
provide a first series of Q-component samples at the predetermined symbol rate and a
second series of Q-component samples that are intermediate to the first series of Q-component
samples and at the predetermined symbol rate. A processor (20) processes the
samples to estimate a phase-adjustment value  A  and a symbol-timing-adjustment value
ST A . The phase of the reference signal (22) is adjusted in accordance with the phase-adjustment
value  A  and the timing of the sampling is adjusted in accordance with the
symbol-timing-adjustment value ST A .

Patent EP-0769781-A3 (EP)
Inventor: SPURBECK MARK S
IPC: G11B20/10
Filed: 1996-10-18
Abstract: A sampled amplitude read channel reads information stored on a
magnetic medium by detecting digital data from a sequence of discrete
time interpolated sample values, the interpolated sample values
generated by interpolating a sequence of discrete time channel sample
values generated by sampling pulses in an analog read signal from a
magnetic read head positioned over the magnetic medium. A write VFO
generates a write clock for writing digital data to the magnetic
medium at a predetermined baud rate for a selected zone, and upon
read back, the write VFO generates a sampling clock at a frequency
slightly higher than the write frequency. A sampling device samples
the analog read signal at the sampling clock rate to generate a
sequence of discrete time channel samples that are not synchronized
to the baud rate, and the channel samples are equalized by a discrete
time equalizing filter according to a predetermined partial response
(PR4, EPR4, EEPR4, etc.). An
interpolating timing recovery circuit (B100),
responsive to the equalized channel samples, computes an
interpolation interval τ and, in response thereto, generates
interpolated sample values substantially synchronized to the baud
rate. The timing recovery circuit
also generates a data clock (B104) for
clocking a discrete time sequence detector (34) which detects the digital
data (B102) from the interpolated sample values. In a cost reduced
implementation, the interpolation filter coefficients are computed
in real time as a function of the interpolation interval τ.
