Title: Source follower circuit
Inventor: MAKABE TAKAYOSHI
IPC: H03F3/50
Filed: 1984-09-03
Abstract: PURPOSE:To reduce power consumption and to improve the transient response characteristic by providing an inverse amplifier amplifying inversely an input signal inputted to a gate of a source follower transistor (Tr) and coupling its output and a gate of a current source Tr by a capacitor. CONSTITUTION:PMOSTrs M3, M4 are added to a conventional circuit as shown in figure. The M3, M4 constitute an inverse amplifier. Then a gate of a current source Tr M2 and a capacitor C are connected to an output of the said amplifier. When an input voltage Vin gets higher, a load capacitance CL is charged quickly. When the voltage Vin reaches a voltage or below, the polarity is inverted by the M3 and the signal is amplified by a gain decided by the mutual conductance ratio of the Trs M3, M4. When the amplified signal is fed to a gate of the Tr M2 through the capacitor C, the current of the Tr M2 increases temporarily. Thus, the electric charge in the capacitor CL is discharged quickly and the response of an output Vout is quickened.

Filed: 1989-07-19
Abstract: PURPOSE:To decode a main signal into a signal before pre-filter is applied by applying inverse filter with respect to the pre-filter used at a sender side to an output and the main signal to obtain a sequential scanning signal. CONSTITUTION:An inter-field interpolation signal is obtained from a main signal by using a delay device 18, an adder 19 and a bit shifter 20. An auxiliary signal whose delay is adjusted by a delay device 21 is fed to the interpolation signal at an adder 22 to obtain a value before pre-filter for a scanning line shown in white round in figure. On the other hand, since the scanning line shown in black round is a signal after pre-filtering, the processing of applying inverse filtering with respect to the pre-filtering used at the sender side is realized by delay devices 23-25, bit shifters 26-29 and adders 30, 31. Thus, the scanning line in black round is a signal before prefiltering. Then both the signals are converted into a sequential scanning signal by a scanning conversion memory to obtain a desired signal.
