Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
119 words
AN INTEGRATED CIRCUIT COMPRISING IN COMBINATION: A SEMICONDUCTOR DEVICE HAVING INPUT, COMMON AND CONTROL ELECTRODES FORMED ON A SUBSTRATE OF SEMICONDUCTOR MATERIAL; A PAIR OF INPUT TERMINALS FOR APPLYING AN INPUT SIGNAL VOLTAGE V1, A PHASE SHIFTING NETWORK FORMED ON SAID SUBSTRATE AND CONNECTED BETWEEN SAID INPUT TERMINALS FOR DERIVING A VOLTAGE V2 HAVING A PHASE AND $ WITH RESPECT TO SAID INPUT VOLTAGE V1, SAID PHASE SHIFTING NETWORK INCLUDING RESISTIVE CIRCUIT MEANS AND CAPACITVE CIRCUIT MEANS, MEANS FOR CONNECTING SAID INPUT AND COMMON ELECTRODES TO SAID PAIR OF INPUT TERMINALS, AND CIRCUIT MEANS COUPLED TO SAID CONTROL ELECTRODE FOR APPLYING SAID VOLTAGE V2 SO THAT THE NET CURRENT FLOWING THROUGH SAID INPUT TERMINALS LAGS SAID INPUT VOLTAGE V1.
